Congrats, dudes. This will truly be one of the most significant and immortal pieces of our pop-culture to which OCR could ever have possibly contributed. It's an incredible gig to score and I don't doubt for a second that the soundtrack will be amazing and classic... and it needs to be: HD Remix (a.k.a. SFHD) is poised to stand the test of time.
I'm sure you're all familiar with SF in general, but I wanted to explain this "immortality" in detail for anyone here who hasn't looked into the hardcore (competitive) fighting game scene.
SF2 is the game that defined its genre, the very first game to really make the versus fighter its very own genre of game. The genre itself is one of the few genres that is still commercially viable today without having had any fundamental alterations to its format since that conception. The original Super Turbo (abbr. ST) is overwhelmingly considered the definitive version of SF2 by the community. People still flock to ST for tournaments almost fifteen years since the release of that specific iteration, and almost twenty years since the first SF2! Very few other fighting games can boast anything this impressive. Years younger than StarCraft and Counter-Strike, I actually don't think there are any other video games its age that still hold such a large active player-base, and it's shown no signs of dying any time soon. Despite waxes and wanes in popularity over the years, fighting games today are still thriving. The vast majority of the fighting game community expects that, assuming it all plays as well as it seems like it will, HD Remix will replace ST and become the defacto SF2.
HD Remix will in all likelihood be one of the very few titles in the history of gaming that will still be widely played years (probably decades) after its release. It's as nerdy as it is epic. OCR has certainly become somewhat legendary in its own right, but I want to emphasize that it will now be prominently featured in something that will last (in the eyes of our modern civilization) forever.
