I have completely given up on Sony when it comes to press events. They either announce the games beforehand which destroys the wow factor or somehow it leaks through.

Sony always has the best presentations and games to show but there is now surprise factor. The last would be FF14

obvious joke is obvious.......................

So you knew about Agent?

No, this is clearly just another display of Sony's inability to plug leaks. It's part of the reason why I'm not sure PSP2 will be aannounced - it hasn't leaked yet.

No. That Logo totally threw me by surprise and blew my mind. Most exciting review ever!

/sarcasm

Just because they announced the big titles doesn't mean they have shown us a lot about them if you really think about it...
for example
A trailer for KZ3, Agent would be epic win! Especially if they give us some gameplay as well
LBP2 hasn't shown us ALL it can do as of now either
Move will get some solid titles as well, they always have given us some amazing games on all of their consoles, can't see why Move will be any different (starwars game plssssss)
Agency! Give us more info/gameplay etc and also DC universe info
And of course there are the surprises ;) They always manage to sneak in one or two of them so it's all good

LBP 2 and Killzone 3 were not leaks, they were announcements.
GT5 has been known for too long for anyone to care if they give us info now or at e3, personally i'll be estatic whatever day they blow-out GT5 ( if its between now and E3)
PSP 2 - people have been speculating about this since forever. But Sony has never confirmed or denied (obviously).
I'm not sure about that insomniac thing

This is besides the point though, Sony still has lots of previously announced things they can show( Agent, Last Guardian) and i doubt they won't have some surprises. So no I don't think they're making these announcements to make space for Move... at least they better not be.
