The jump will be as big as the one from Xbox/PS2 to Xbox360/PS3, or a little more due to this generation lasting more than the last one.
Yes, I know that both Microsoft and Sony said that they can't assume the looses they've had this gen, but just for the bragging rights and the fact that they don't know the real plants of the other, will make them launch a console as poweful as possible.
And, as the resolution of the screens won't change, other features as 3D, tesselation, etc. will be more important.
Please excuse my bad English.
