The only real difference between their strategy this gen and last gen up to this point was that they showed a little bit of game footage from Killzone, Infamous, and Knack.
The PS4 reveal and Cerny's GDC talk were very similar. "here's the architecture, here's the problem with the cell, here's how much ram it has, here's the TFLOPs, the time to triangle, more news later".
They had alot of 3rd party games at the PS4 reveal but those were pretty much just "here's some stuff you've seen before but there's a PS4 logo this time".
