will the graphics of next gen blow away this gen's graphics (i don't pc game maybe it's already being blown away)? if not, then does sony really have to release a new console because MS does? why can't sony work on a 10 yr plan for the ps3 or at least release the ps4 in 8 years? why can't MS do the same thing?
i'm sure both companies are working on something, but i'm also certain that they are looking a lot closer at what they are including out of the box because noone wants to replay the ps3 launch.
also, i agree that game development costs have increase so much that longer life spans would be appreciated from the developer's point of view (regain initial development costs).
