The next generation devices will get brand new processor by Qualcomm! It will offer single-core, dual-core, and quad-core processors clocked all the way up to 2.5GHz plus a new GPU!
We don't even get to taste yet on 1.5GHz dual core and yet 2.5GHz is coming. Yes, patient is killing. Technology is growing fast. Obviously, i am more looking forward to quad core tablet than phone ;)
