While players on the PlayStation 3 are currently able to pre-order Ultra Street Fighter IV’s digital upgrade right through their console, folks who own the game on Xbox 360 will need to look to Gamestop to fulfill the same purpose.

The video game retailer’s website was updated earlier today with the details. Much like on Sony’s console, the digital upgrade for Xbox Live will run customers $15. Unfortunately, where Ultra will arrive on PlayStation Network on June 3 at 12 AM PDT, Xbox Live will not receive the update until later that morning at 7 AM PDT, though this does conflict with previous reports that the game would show up on Xbox 360 the following day.

Pre-ordering the Ultra upgrade will grant you access to the five alternate outfits designed by Udon for Decapre, Elena, Hugo, Poison, and Rolento, all of which are featured in the trailer below. The code for these costumes will be emailed within two days of purchase or printed on your receipt at the store, depending on which option you choose.
