If only they would do something like that, simple fact is there not "miles" off the pace with the old technology there using so if its cheaper to keep shrinking it and ramping it up it means there R&D money can be spent elsewhere, and IIRC there aiming at other bits and bobs and not concentrating on CPU's..
Nothing to say they wont turn round in a year or so and start from the ground up, maybe there doing it now hence the lack of new real features etc, no point spending shed loads on the old stuff so they take the cheap route, shrink it, ramp up the clock, add more cache, all pretty simple things, yet in the wings theres something new on the burner....
