Yeah, I made thread about this already. We've known for a while that it'd have a built-in HDD, and that it'd lack a UMD tray.
What I wanna know is whether it'll be a whole new platform or not. I mean, if they enhance the graphics, not only will the system and games cost more, but they'll also take a lot longer to download.
And if they soup up PSN, the only way they'd add in a lot of the features of the PS3 iteration is with a 3G network. And with the above-stated graphical enhancements, that could cost us as consumers A LOT of money.
So yeah, I think this will just be an enhanced remake like the DSi.
