Here's my 2 cents:
Personally I've been wishing for (and it probably continue to be just a wish unless I make it myself) a true FPS/RPG hybrid but NOT in an MMORPG style and definitely not swords and sorcerors. I'm thinking something more like Fallout from a first person perspective. Like Fallout as in: experience for kills, standard text dialogue with multiple options for responses, nifty customizable stats for you the hero, skills that go up with levels and not by taping down the use key, random encounters, etc. In other words, a standard stat/level based RPG but from a first person perspective for more immersion.
edit... geeze... I took so long writing out my reply that this thread grew a few "we'd like FPS/RPG" while I typed..... good to see I'm not alone
