Hey the offical release date for singstar is 07/12/2007 (7th December 2007) as it says on Game site and Game never get the release date of a game wrong! NEVER! anyway here is the link for you to check it out for yourself
This has got to be at least the third rescheduled release. Frankly, at this rate, I'll believe it when I see it because I've had this game on pre-order since May! By the sounds of it, most of the songs on the online store (99p a song so beware!) are from previous PS2 Singstar titles anyway. Oh well, I'm sure it'll be worth it in the end!
