Final Fantasy XIII and Halo 3 at E3 This Year?

There are hints floating around already at some of the titles that will be unveiled during this year's Electronic Entertainment Expo. 1up has a short piece saying that Final Fantasy XIII is almost done, and will get a powerful debut at the show in May. IGN, meanwhile, is rumourmongering that Halo 3 will also make an appearance. Not only that, they say, it's slated for a March 2007 release. From the article: "By theoretically shifting Halo to next spring, Microsoft thus allows third-party companies a better chance to shine independently of Bungie's uber shooter during the fall 2006 season. One must wonder, however, why the game wouldn't come out simultaneously with the movie, due in summer 2007. But if Halo 3's alleged March release date is officially confirmed, perhaps the game will leave questions for the movie to answer."
