It's way too early to say the will finish much bellow last gen numbers.

They still have XIII-2 which will sell 3-4 milions worldwide at least
Versus XIII which will do at least 5
Type-0 which is easily milion seller
Dragon Quest X - which should bring at least 2 milions even with the Wii collapse worldwide (unless it goes directly to Cafe)

Plus since they are on E3 sony conference you can bet on SE jumping into HD collection releases which will add another milion or two if they put X,X-2,XII collection (or another 5 if they have remake of VII ready ;) )

Maybe this is why they bought Eidos, they needed more games, but they have had some solid hits with the PSP, even in the West, but they do have XIII-2 coming this year which should sell nicely, and Versus is another big title coming at some point, but they have really lost their way, they just seem to take forever to release games
