An interesting ESRB entry just popped up recently in the ESRB game ratings page, and this time it's for a Warhawk title that is slated for both the PS3 and the PSP.
Given its E rating, and the fact that its for both the PSP and the PS3, it seem very likely that this will be the very first Warhawk game, which may become available online via the PlayStation Store.
The first Warhawk game was introduced as a launch title for the PlayStation One. The SingleTrac-developed title was originally released in November 1995.
