Sony revealing games pre-E3 just damage control?

[Torillian]

So far everything they have announced are pretty expected or heavily rumored sequels, so I think it makes sense to announce them before the big show when they can get covers on magazines and be the talk of the internet for a while.  Hopefully they have a few more unexpected announcements for the actual conference that will actually be surprising enough to warrant attention during E3.  I highly doubt that "this is it" as you put it.
