These screenshots are not final, but they are probably a better representation of Super Street Fighter II Turbo HD Remix compared to the leaked footage from London. The new graphics are looking sharp and I dig the new character portraits.
In the same post, Capcom mentioned Super Street Fighter II Turbo HD Remix is based off the Super Street Fighter II X Dreamcast code. Capcom assures that the even though the source is not the original arcade code, Super Street Fighter II Turbo HD Remix will be a replica of the arcade game. The reason why they chose to use the Dreamcast code was it had online play and matchmaking built into it.
