Seriously, every single slim model was the revision of an already successful console. Even the PSP was a modest money maker for Sony which allowed them to have that extra $$$ to invest into the R & D to develop the PSP 2000 and 3000. Was there a Game Cube or Xbox light/slim released several years ago? No, because the sales were poor to begin with. yet people keep assuming that Sony will release a Slim version in the nearest future, which means they must be working on a slim concept right now. Now how likely is that?
