A Halo-based announcement may be coming sooner than we think, developer 343 Industries has teased in a Halo Waypoint Tweet.
The official twitter account quoted and retweeted a fan photoshop of Master Chief (from Halo 3) in a car's wing mirror.
"Objects in mirror are closer than they appear!" teases the Tweet.
It's believed that Halo 2 Anniversary is next on the Halo release slate, followed by Halo 5 either late this year or in 2015.
