Here's the deal: Motorola is announcing that they made a protocol that is used for PTT over rev A. This is what Verizon is using for their new PTT service...whether or not Moto made the phones is totally another topic.
BTW, whoever said iDEN was slower for PTT? Data yes, PTT no. Qchat (developed by Qualcomm for Sprint) is slower than iDEN PTT, and Moto's PTT is slower still, since it's running in the software layer rather than being an actual modification to rev A protocols (Qchat). All in all, we're still talking about connecting in about a second on Qchat and iDEN PTT, so they're both pretty similar performance wise. Not sure on moto's solution, but I'd bet it's very close too.
As for sound quality...Qchat and iDEN are pretty even IMO, so not sure if that's what the comment in the story was about. If it was about Verizon and Sprint (CDMA)'s old PTT services, then yeah, they sucked.
