As of now PSN does not have any new demos, but the new trailers are sure to keep gamers happy for a while. Along with these trailers, the full E3 conference was expected but that has yet to show up.
Stay tuned to PSU for up to date E3 coverage!

That's nice but what I want are demos and games... Not trailers... Oh well.
