Through 2015, probably 16-18 million in sales. If it hits 20 I wouldn't be surprised but that would require a price drop at some point, which Nintendo never really did with DS games.
if ya want your prediction up you need to give me an answer for this years life sales!!! BTW i think your right on life time sales by 2015!
Hmm...it's at 5.20 right now... I'll say at 8 million by the end of 2013.
ok cool adding you now. Me thinks 8mil minimum buts its just my opinion!
