This is what 1up have to say about the event,
I firmly believe that, despite Sony's parade of "we don't pay for exclusives" comments over the years, that they have firmly supported S-E in the development of FFXIII (and it's ilk) in order to retain console exclusivity. I'd be very surprised if that changed. I think S-E is content to let tri-Ace do the heavy lifting in supporting the 360 with its content, and I was pretty underwhelmed by the 'RPG conference' as a whole. No real surprises. I mean, I love tri-Ace, and think these announcements are great, but it felt like the 360 got the B-team, while the A-team are free to frolic away on the PS3. Just my two cents.

So true 
So4 and LR will come to PS3 but what about games which S-E best teams are making? They will never port it to 360.
