Yesterday we found that Audio Surf was supposedly making its way to the Xbox Live Arcade via GamesTM Magazine. Well apparently that's not so much the case, as Dylan - developer of Audio surf - had this to say on the Audio Surf forums:

Must have been a miscommunication. I didn't say that.

Wah-Waaah. He didn't say it'll never come to XBLA, right?!?!

Though it appears there are no plans for it to make the jump, Audio Surf absolutely feels like an XBLA title - the 'simple' design and pick-up-and-play action of the title would definitely work within the XBLA library.

The game could support MP3 playback from USB Memory Sticks, and much like the Steam version which included the Orange Box soundtrack, could include a bunch of classic Xbox music (nerds around the world would love to play with the Halo theme, maybe Banjo Kazooie theme), or if they're smart, team up with EA to allow the same music selection available for Rock Band to be played on Audiosurf!
