I agree to a point. I think that they will make tweaks like the PS2 and PS3 will do. But the major redesign will only happen once more for the 360. This will kill hurt M$ bad. I say, HA HA!

The PS3 will get larger hard drives but cost the same. The tweaks will be 65nm chip (cooler and cost less) and maybe a faster blu-ray drive (3x or 4x) for faster loading. But nothing major. It's already future proof.
