Is EV-DV dead?
Whatever happened to EV-DV? In 2003, when Verizon opted to pursue the EV-DO path, Sprint initially snubbed EV-DO in favor of the more efficient EV-DV path. Of course, while Sprint waited upon EV-DV to be developed, Verizon launched EV-DO and it became clear that if Sprint did not get into the EV-DO game they would fall far behind. Sprint did enter the fray and quickly launched EV-DO. Sprint's progress is quite impressive considering its late start. Now that EV-DO Rev A with VoiP is the latest standard, I wonder if Sprint will still pursue the EV-DV path? This is further complicated by Wi-MAX. I am still of the opinion that the Nextel merger was a mistake and am unsure if Sprint is not simply being stubborn. It seems that they are spr...

The EV-DV standard was dropped by Qualcomm itself due to lack of interest and development. It is dead and will not be resurfacing in any manner now that EV-DO has had the time to be deployed, tested in real life situations, and modified into newer release versions such as Rev. B and Rev. C which are both much more efficient than EV-DV ever would have been.
As for Sprint "bowing" to market pressure...it was no longer an option offered by Qualcomm so it was not available for them to deploy.

what was the main difference EV-DO vs EV-DV?? EV-DV could handle voice and data at the same time??

Exactly. And now that isn't a problem with future releases of EV-DO considering they are intended to be used with VoIP and have much higher data rates.

I also don't think that EV-DV was going to be capable to handle the 'wide pipe' data rates that technologies like WI-MAX seem better to handle.
This is why you see Qualcomm picking up or pumping out a variety of underlying technologies for the standard, I think EV-DV was DOA simply because it lacked potential.
