HALO developer Bungie linked to a “mysterious” image (seen below) on Twitter and told followers that “something big is dropping this week”. The image shows a zoomed-in Spartan helmet with lights on either side. Some have speculated that it could be a new trailer for Halo: Reach , some have even gone as far as thinking it could be an announcement about a movie finally in the works.

Considering the timing, and the fact that the folks at Bungie have a sense of humor, it could very well be an April Fools joke.

Bungie has previously confirmed that Halo: Reach will be the final project in the Halo universe.
