Simply put, this piece of news is of interest to those cellular network operators in the world who currently operate WCDMA networks or those who are thinking of installing one, not those who are interested in other technologies.
Coming back to this story, higher order modulation like 64QAM, when combined with 2x2 MIMO, helps reduce the gap between the spectral efficiency of HSDPA and LTE systems. It is an incremental improvement which is of significant importance to those network operators who do not yet want to invest the financial resources required to roll out a new LTE network right now, or those who simply cannot afford to swap out their WCDMA network for LTE for many years to come.
If you see this announcement from Ericsson in the right light, it actually makes a lot of sense.

evengrift, there's an engadget article from yesterday announcing EDGE Evolution from Nokia Siemens Networks : http://www.engadgetmobile.com/2008/03/27/nokia-siemens-rolling-out-edge-evolution-for-double-the-speed-in/
You won't find me on that post denouncing the technology because the rest of the world has moved on. I'm sure the incremental improvement being offered will be of value to some operators.
