Back in 2004, Microsoft released what many believe to be the best in the Halo series: Halo 2. Ten years later, and the rumor mill is buzzing with anticipation of a Halo 2 Anniversary Edition announcement, with the hope that it'll arrive on the Xbox One in full high definition glory later this year. The rumor originated on NeoGAF. If true, it does seem to throw a wrench into the previous plans, where Microsoft has promised to release Halo 5 in 2014. Microsoft likes to spread out Halo releases, so if a Halo 2 reboot is set for 2014, it wouldn't be hard to believe that Halo 5 would be pushed back to 2015, resulting in much disappointment. We'll update when we hear more.
