i'd be putting my money on KOTOR 2. why? becuase we know that obsidian is working on a known franchise, on PC and conlsole. And that they have a deal with BioWare. Now how many publishers are going to trust their beloved franchise to an unknown developer (regardless of personell)?
But as they have a deal with Bioware, and are working on known franchise KOTOR 2, or NWN 2, and the inclusion of console would sway me towards KOTOR 2.
But i could be really wrong
