That news was incorrect. Sony's said so:

“That last feature included interviews, footage from CES 2010, and a brief montage of SCEA titles intended as examples of what 3D gaming might encompass. It is hard to do justice to just how amazing 3D gaming looks in a 2D presentation—even in an HD product such as Qore.

"Unfortunately, our feature did not make it clear that the 2D game footage was included for demonstration purposes only. We apologize for the erroneous inference that 3D versions of LBP, Wipeout HD, Killzone 2, Gran Turismo 5 or Super Stardust HD are in production.”

We betcha Killzone 3's in 3D though. Just sayin'.
