I'm still going with Bioware, though personally I'd like to see them both work on it, both companies have areas where they are going to be somewhat better then the other.

My biggest issue is that Obsidian ended up getting rushed with KOTOR 2, and while I enjoyed that game, I liked KOTOR better, the gameplay was well-balanced compared to KOTOR 2; and personally I loved the storyline for it, it may not have been as original, but it was better written.  And hell, I'll admit, my favorite NPC was Juhani, and I think only Bioware would give us something like that again, though if Obsidian could prove me wrong, that's cool too.. Either way I know I'll be buying it for PC when it comes out.
