I'm excited for none of those, all of them are "wait and see" for me. The only one that almost definitely deserves excitement is Reach (as the final Bungie Halo game), but the rest on that list (besides Metroid perhaps) are all going to be over-hyped to oblivion. I've learned to not trust Moleneux, Medal of Honor is a mess so far, and I'm hoping and praying that Obsidian doesn't ruin Fallout, but it is only a fool's hope.
