Whoa, I never realised it was so close. Well 2.6M vs 4.1M isn't that close, but they'll be in the same league very soon at this rate.
Currently I believe a newer and better, yet similar in target audience and approach, game will be released during the next six months and largely replace Wii Sports as the game everyone buys when they get a Wii. Of course I might be wrong, seeing how both versions of Brain Training are still selling truly insane amounts every week.
