Though official media reports are going to be silent on the event held yesterday until about 5pm Pacific Standard Time, word of what may be expected to be reported is already breaking across the channels. From an inside source, a small list of titles was sent to me with claims that this list was the actual list featured at Capcom Gamer's Day.
Wii
Resident Evil 4 Wii Edition
Resident Evil the Umbrella Chronicles
Treasure Island Z
PS3
DMC 4
Xbox 360 - All three of these games are Xbox Live titles
Rocketmen (described as a Smash TV esque game)
Super Puzzle Fighter II Turbo HD Edition
Super Street Fighter II Turbo HD Edition
PSP
Monster Hunter Freedom 2
PS2
MotoGP
DS
Phoenix Wright Trials and Tribulations (4)
Megaman ZX Advent
Megaman Starforce (3 editions)
PC
Lost Planet
Though we expect no confirmation on this list until this evening, seeing both Super Puzzle Fighter II Turbo HD and Super Street Fighter II Turbo HD for XBLA is a great choice on the part of Capcom for release on the Xbox Live Arcade (should it prove accurate). However, it does bring up the question of whether or not Microsoft is going to take any effort to ensure that Street Fighter Anniversary Collection is ever added to the Xbox 360's backwards compatibility list.
Shoryuken.com currently is doing their part with an e-mail letter writing campaign to Microsoft's backwards compatibility team asking for just that. If you haven't had the opportunity to e-mail Microsft yet, I would definitely recommend taking a few moments and requesting Street Fighter Anniversary Collection be updated on the playable list for the Xbox 360.
I'll be keeping an eye out today for more information that's released prior to this evenings media blitz. If anything new develops, you'll be sure to see it here.
