I'm sure it wouldn't sell as many copies, but I'd rather that they went back to the old CRPG style of RPGs instead of a fully 3D game. They've always been far more enjoyable for me.
If you like ones that focus on tactical combat and are a fan of 3.5 D&D....Knights of the Chalice 2 just came out. And there's a toolkit for making adventures NWN style, so I'm hoping we see some good user created content as well.
As a fellow cRPG fan, I wouldn't worry too much about losing devs like Obsidian and InXile..
