In hopes of bolstering its PSP PSN download scene, Sony plans to expand its digital catalog to include non-PlayStation console titles. "In general, there's a lot of discussion about [publishers'] back catalogs that will finally find its way to PlayStation Network in the back half of this year," said SCEA's John Koller to MTV Multiplayer. That would include both the promise of more PSOne titles (as North America seriously needs to catch up to Japan in that regard) and pre-PSOne retro titles.

Despite becoming more Virtual Console-ish, this expansion of the PSP side of PSN will also offer more portable versions of PS3 downloadable titles, such as PixelJunk Monsters and the already released Super Stardust Portable. Koller says that Sony's studios are preparing more internally developed download-only titles. This strong focus on digital distribution makes us wonder if the whole "dropping UMD" rumors are true.
