The 28th to 30th November Xtival '08 will take place on Xbox Live.
There'll be competitions, tournaments and events, but best of all, there'll be free live gold-membership the entire weekend.

that would be cool if they would give us three extra days for those who already have a gold account.

Yeah, I was actually planning on buying a 12-month gold membership, but I think I'll wait 'til after Xtival now.

yeah i wish they would add 3 days to my gold

Sweet. There's going to be a lot of people online.
