I guess for them wheres their motivation, as ogles2.0 is good enuf
Not sure if any companies think this way, but if they do they should change their perspective.. because anyone knows that the hardware support has to drive adoption, not the other way around.
But I don't think that OEMs are choosing old or very underspec'd SoCs for their new phones because they see no demand to do any better but because they're racing to the bottom in price. The big surge in phones with 2007-2008 level CPU and GPU capabilities is basically coming at price points where they're replacing old feature phones with something that can actually run Android.
