The three new titles this month happen to all be downloadable titles, but are all great nonetheless.
This is for the US, also. No news on what the EU games will be.

Edit: I myself am excited to finally get my hands on GC Impostors after really liking the beta. Already own Pac Man CE DX and Renegade Ops on XBLA but will be glad to jump back into both.
