PS4 to launch in JP and US in 2013, and in EU 2014? More powerful than x3ox and with small touchscreen in new controller?

[UnknownFact]

"Privately, Sony representatives have conceded that the company made a mistake in creating such esoteric architecture for PS3, and its strategy for PS4 gives developers more opportunities this time around, notably because the hardware is much more PC-like in its makeup than PS3."

Which means no backward compatibility (BC) with PS3. I wonder if there will be BC with PS2. Shouldn't be hard to do.
