Saw this news yesterday in Wii-U's perspective, but was afraid to post it, as I though it was disscussed ages ago, I'm not quite following this PS4 stuff.
I think it's too early for next-gen consoles. I'm quite happy playing PS3 nd Wii games, as are many of you too. Previous sony consoles introduced a huge jump from it's predeccessors - PS1 (one of the first 3D console), PS2 & PS3 (huge jump in graphics and sound, internet play, processing powers etc). Not to say, that every next Sony console had new storage media - CDs, DVds, BDs.
What can PS4 possibly introduce? More processing power? Nope, not quite interested. New media? If it's only digital downloads, then it would also be a fail. Something shiny like touch screens and gyroscopes? Stop copying Nintendo. They have this market segment.
I can't really think of awesome new ideas for PS4, sorry Sony.
