With a readily growing Wii userbase in America I think this could see higher sales then previous titles. Especially seeing that it's coming out with its only competition being Madden 08 which on a Nintendo platform has never been strong competition for a Nintendo game.
I'm going to kinda go out of the box here and think a little bit higher numbers. For one there is quite a fanbase for the Metroid games. Reason first week sales on 1 and 2 Prime weren't so high is becuase it was a resurrection of a series and then an underhyped/overclouded Echoes title.
This time Metroid 3 is in the clear, part of the triforce of bit Wii games, and has a huge, loyal fanbase. I think this could be the best selling Metroid game ever.
So as I said goign to jump a little out of the box of others and take a larger guess:
1st week- 400k
End of Sept- 900k
End of the Year- 1.5 million
All for America. It'll probably also sell better in Europe. Possibly a million in its lifetime there. In a lifetime in America possibly over 2 million. In Japan about the same. 100k maybe. So I think this could go triple platinum.
