Sega still has some arcade games they need to release on consoles. I want a Virtua Cop Collection for PS3+Move and Wii U (and 360 using that Cabella lightgun or something).
Namco, Konami, Capcom, et al. should be milking this shit too. Throw up Police 24/7 (aka 911) 1&2, Resident Evil Dead Aim, Time Crisis Collection, Point Blank Collection, and all that stuff. Silent Scope games are iffy when you drop the gimmick but Wii U is a decent approximation the arcade experience.
And I can't believe Die Hard Arcade, or any of the Deka games, haven't been put on XBLA/PSN yet.
on the bright side, arcade emulation is chugging along. Model 2 is quite good and a couple Model 3 games work with graphical glitches.
