Wow, it looks like someone was listening when we said that Pivot wasn't going anywhere just an hour ago -- Comcast, Time Warner (Engadget's parent company) and Cox have all confirmed to the AP that they've backed out of the quad-play partnership, leaving Sprint alone to awkwardly hang out with Advance / Newhouse, which declined to comment. That must be a fun party. Of course, this also means both of the partnerships Sprint and Big Cable got into have now failed, but that doesn't mean the competition in the space is over: both Time Warner and Cox say wireless is still in the cards for their companies, but Pivot was just too complicated a venture. Comcast hasn't said anything yet, but promised a comment tomorrow sometime between 7AM and 11PM.

We're not exactly willing to sign up for even more punishment at the hands of Comcast, but all you masochists in the crowd should take note: GigaOm is reporting that the cable giant is "serious" about offering wireless services and has hired former Telefonica O2 Europe CTO Dave Williams to make it happen. It's not clear what type of wireless is being considered, but it's a good bet Sprint will be involved somehow: Comcast is still in that goofy partnership with Sprint called Pivot that hasn't gone anywhere, the two companies are rumored to be talking about a nationwide WiMAX network, and GigaOm thinks there's a chance it could up and buy the struggling carrier outright. That would be quite a move, but it's all just speculation for now -- we'll let you know if we hear anything solid.

As unlikely as this sounds, rivals Time Warner Cable and Comcast are apparently in talks with Sprint and Clearwire over establishing a nationwide WiMAX network. According to a report in the Wall Street Journal, the companies are scrambling to get a deal wrapped up by CTIA -- which takes place at the beginning of April -- and could see an influx of cash from both Google and Intel in excess of $1 billion. It seems the odd-couple partners are keen to cut into heavyweights Verizon and AT&T's ever-expanding range of at-home and mobile services by offering their own take on a high-speed data and voice system to consumers. Clearly this combination would deflate AT&T and Verizon's big FCC bandwidth-nabs a little (and it explains why the cable players weren't interested in the 700MHz auction), but it's questionable whether this rag-tag team of wild card players would seriously court the public's eye. They say America loves an underdog -- even if it's a gigantic, super-rich, corporate underdog.

In what is surely a sign that the mania around the upcoming 700MHz auction is reaching absurd levels, cable operators Comcast and Time Warner Communications both issued press releases today confirming that they would not be bidding in January's auction. You might recall that both Time Warner (which is owned by Engadget's parent company's parent company) and Comcast are part of SpectrumCo, which snapped up 137 licenses covering 20MHz of spectrum the last time the FCC put airwaves on the block, so there was some speculation that the venture might ante up again this go 'round -- especially since TWC CEO Glenn Britt was running around making vague proclamations about it. Still, it looks like Sprint's exit from the alliance was enough to shelve any such plans, so it looks like the big players are still Google and Verizon. Good thing too -- with this much hype over Good vs. Evil, the racket over Good vs. Evil vs. More Evil vs. Frustratingly Incompetent would be deafening.

Yeah, Sprint unveiled the UpStage today, but the other sorta big news is that they officially took the wraps off of Pivot, the new name for their new quad-play service bundling up wireless, voice, broadband, and cable TV as a single package (they've been offering service in a handful of markets for a while now, they're basically just rebranding everything). Sprint's partners in Pivot are a handful of different cable providers, including Comcast, Cox, and our arch-nemesis Time-Warner Cable (which is owned by our parent company's parent company -- not that it's done a damn thing for the totally awful cable TV and internet service we get at Engadget HQ). All the big telcos are pimping these triple-play and quad-play packages -- they see them as a way to lock-in subscribers by offering them lower prices than consumers would pay for each service separately -- but Sprint's big selling point is that they're also promising some intergration across services, like the ability to program your DVR box from your cellphone (which we've already seen from AT&T), check home email and voicemail from a single interface, and make unlimited calls between your home VoIP line and your mobile phone. Anyway, Pivot is currently available in eight cities now, with another 40 more set to launch this year. Pricing will vary by market.

BusinessWeek writer Olga Kharif paints an interesting portrait of the potential state of the wireless industry following the government's unprecedented sale of spectrum this summer, called Auction 66, which could see a number of new players enter the voice and data market in the not-too-distant future. Following several years of industry consolidation, highlighted by Cingular picking up AT&T and Sprint grabbing Nextel, we could soon see companies that have traditionally delivered content in other fashions -- Time Warner, MySpace-owner News Corp., or Clearwire -- offer services that compete directly with the four major carriers. Several players, including Intel-backed Clearwire, Google-backed Earthlink, and a venture between Time Warner Cable, Sprint-Nextel, Comcast, Cox, and Advance/Newhouse Communications have already expressed interest in bidding for a slice of spectrum, while other bidders, which could include a Bill Gates- and Paul Allen-backed contender, will be revealed sometime next month. Unless the established carriers snatch up all the available spectrum, which is highly unlikely, fresh blood in the industry should bode well for consumers, who will likely benefit from lower prices, more services to choose from, and less restrictions on their bandwidth usage.
