Three FPS Battle It Out for Game of the Year

I'm not a big fan of First-Person Shooters (FPS).  Yet, three games collide in 2007 that peak my interest, and that's no easy task.  Halo 3 is the clear front-runner in hype, at least.  I'm not running out to get this one right away, I may wait for Xmas.  Bioshock is the new baby that may just knock Halo 3 into the penultimate spot for best new FPS?  We'll see, but I love Bioshock.  It's pretty and also a competent game that is scary fun.  The third game is most likely going to be my personal favorite, because it will have a ton of variety, a good story, and a good time for the non-arena kind of guy that I am.  That would be The Orange Box (Half Life 2, Eps. 1 and 2, Team Fortress 2, and Portal).  This last one isn't a single game, but it's a great value!  It kind of lost the originality or descriptive game title contest, although the box is orange, after all.  Are there any other FPS out there that I should check out?
