Well I need to see how Brawl will do in it's first holiday season and then Galaxy in it's first that wasn't close to release. If they are able to come out of this year with over 8 million in sales then it's pretty obvious they would go deca platinum. For the next 40 weeks they'd sell at least 20,000 which accounts to another 800,000 in sales in the year. And then 40,000 a week for 8 of those remaining 12 weeks which stacks up another 320,000. And then finally 4 weeks of 80,000 which accounts for another 320,000. Anyways by the end of 2009 they would be at sales 9.4 million to sell 600,000 remaining in 2010.
Of course if legs dwindle away then this won't happen but it's Mario and Super Smash Bros so I don't think we'd have to worry about that too much.
