Yoshida: DualShock 3 won't work with PS4

"No, [PS4] doesn't support DualShock 3, but it does support PS Move," Sony worldwide studios president Shuhei Yoshida has confirmed. Considering the design of the DualShock 4 and the functionality within, we can't say we're too surprised.

Obviously we knew about the PS Move compatibility, seeing as how it was featured during last night's event, but this is the first definitive word on DualShock 3 support. Last night Sony announced that PSOne, PS2 and PS3 games would be playable on PS4 through technology developed by Gaikai, but that PS3 discs would not work natively.
