The other Capcom game that has been confirmed for PC is Dark Void. The jet-pack-happy science fiction shooter is being developed by previously successful air-combat game developers, Airtight Games. They produced Crimson Skies: High Road To Revenge on the OldenXbox. What we know at the moment is that the game is set in a dimension on the far side of the Bermuda Triangle, has Nikola Tesla in it, and features both hoverpacks and jetpacks, for aerial combat. The trailer (below) isn't much more illuminating about all that, but the game does look both aerial, and pretty (I've posted a couple of new images below) with its Unreal Engine 3.0 environments. Possibly one to keep an eye on.
