Any worthy games of buying on the PSN? Anything worth looking forward too?

I got all excited about the burn zombie burn expansion coming out. But by the looks of the trailor, it's really only new maps.. I was hoping for more game modes, more weapons.
Maybe that stuff will be included, otherwise I hope it's just a cheap map pack.

Nothing new since the awesome summer of psn

I havnt cheked out any of the releases yesterday, I'll wait til next week.
