I think in the future that size is realistic, sure they have already reduced the size of the cell chip and others so its feasible, but releasing one this year?!!??!
I know sales are not great especially in NA compared to 360/Wii but a PS3 lite/slim will not be out for a while yet.
A new SKU is definitely around the corner though at that will be out for xmas and likely another price cut too!
