Starhawk? Yeah, seems like an awkward name to trademark, but considering that Dylan Jobe recently formed a studio of his own (Lightbox) and announced that he's working on a sci-fi space shooter, this is possibly it. I, personally, can think of a better name…it starts with "Colony" and ends with "Wars", oh yeah, you know it. Do the right thing Sony, twist Jobe's arm (if he is the one behind the title) into renaming it to Colony Wars.
In any case, the trademark was made only five days ago on April 9th, so whatever this game is, it's probably still really early in development. Or, perhaps the folks at Sony just settled on a name now. In any case, we know absolutely nothing about this game, besides the logical assumption that this is the next step in the Warhawk franchise.
Hopefully the game is further in development than we think and that Sony shows it off this coming E3. Stay posted, folks.
