I'm more confident in your numbers than tbone's, but I hope he wins. ~_~
Pikmin wasn't really that popular on the 'Cube, but I could see this being the best selling Pikmin game now that the IP has gotten more exposure through SSB and Nintendoland.
Also guys, remember that you have to consider a certain percentage of sales will be digital, meaning they can't be tracked.
I certainly expect sales to be marginally better, though it's hard to say. Sales data for Pikmin 3 has been a bit difficult to track down.
As it stands, I calculated equivalent Japanese sales from Pikmin 2 attach rates, gave them a 10% boost, and then extrapolated for US and Europe from sales distribution. I also gave Europe a bit of a boost, just because.
As far as digital goes, we agreed to set aside digital sales for the purposes of our estimations. I don't know how much of an effect it will have, in any case.
I believe in honesty, civility, generosity, practicality, and impartiality.
