It won't sell a other 7million. It still has some life in it but no way near enough to sell almost more than 1/4 of what it already sold in it's 4 first year.

Look at This http://www.vgchartz.com/game/1254/mario-kart-ds/Global/ MKWii hasn't even got a price drop yet, Wii U has backward compatibility, and its one of the best games with long legs. Expect the lowest 38mil lifetime. Holidays alone in the next two years should boost this up a mil each. MKDS still going strong as well as NSMB (DS) despite them being over 7 years old!!!

I'm not denying any of these facts, but do the math. In order to beat SMB, it needs a other 7milion. 7mil is over 1/4 of the 33mil already sold. Mario Kart Wii launched 4years ago. This means it would need have enough legs to sell 1/4 of what it sold already sold in 4years. It cannot be done. I think it will sell a other 2 or 3mil tops for a total of 35/36mil. Wii game sales are plummeting extremely fast, MKW does'nt have enough time left to sell 7mil. In 2years (if not1) it's sales will be close to insignificant, no way it will sell 3mil a year before then.

I don't think the price has ever been a issue, with 1/3 or the Wii's market owning MK I doubt a price drop will do much of a difference,  almost everyone who wanted the game already bought it.

As for the WiiU factor, expect a Mario KartU in the next couple of years (if not next year).

I see wat your saying, I dont think it'll beat it but i do see it gettin close to 40mil. It doesn't matter about the year its in. The fact alone that NSMB and MKDS is 6 and 7 years old is still selling over a mil. The 5th and 6th year for both selling millions of copies!!!!! MarioKart Wii will sell the next 3 holidays with a mil a piece. The legs even after MKU comes out will keep going. The price cut will absolutely help if cut down to $20-$30 while selling in holidays! Im hoping for 40mil but My guess would be 38mil. Trust me, It can happen, Its Mario

it wont, it needs another 7 million and the WiiU just came out

Even with the wii u, there is no MKU yet and beside MK7 is out and the ds version is still selling especially during holidays! Im not saying it'll pass but believe even with a new mario kart out, this game will continue to sell, Did I mention its still "full price". Just imagine holiday with this for $20-$30

it has 33 million sales. its clearly not about the price. just look at the sales of the game, it fell from 5M last year to 2 million this year. now that nintendo has a new console out people will move to it, and wii sales will drop even more. it will be lucky to pass 1m next year. no way its going to sell for another 7 years and sell another million each year. it outselling mario bros is out of the question

I would bet you (not beating mario bros but at least a high 30s mil number) but this game will take long to reach it IMO. lol. I guess will see next year right?

this is correct.  I want people to justify why they think other wise.
