Meh, that seems to be going a bit too far out of your current field of data for extrapolating, don't you think? The PS3 and Wii have only been out a little under ten months, and you want to go all the way through 25? To me, it's just too unreliable. I mean, the formula for each is no doubt solid, but it's still hard to account for all the surprises and changes in shipment numbers (especially for the Wii) that are to come in the next year. I wouldn't be surprised if your numbers turned out to be relatively accurate, but from a statistical perspective, extrapolating that much will always be frowned upon.
