The link I posted a few pages back seemed to reckon it was going to be a western release too.
edit: kona - it is now yes, now that they've removed the copy protection from the saves. If you use a different account to play though the game will overwrite the save data with new data (to stop you buying expensive cars then sending them to your main account basically).
cheers - i hope it works properly and doesn't messeup up my progress.
