In case you missed our forum topic on the subject, Mad Tracks has successfully made a pit stop, got a full tank, and changed all four tires in 4.372 seconds. And by pit stop I mean got patched. And by 4.372 seconds I mean approximately two weeks.
TeamXbox even goes as far as saying "The update will automatically install at title launch and will have no side effect." Yeah, Microsoft has said that before. Let's hope that comment doesn't foreshadow the announcer's curse like with the console-bricking dash updates of the past.
But who cares about all that. Just go enjoy some racing with your newly un-trial-ified Mad Tracks.
