Street Fighter IV if you consider all of them combined sold around 8m

Mortal Kombat sold around 4m

Tekken 6 sold also sold 4m

Killer Instinct can also prob push around that 4m mark with high attach ratios being a launch game and if you consider the initial download is free it could be downloaded way more than that.  Plus having seasons with new characters it should be revived multiple times giving it legs.

Not saying any of them will outsell Smash Bros 4 but you never really know about these things.

Super Smash Bros Melee sold 7.07m and the original 5.55m. If we are to expect a significant decline in the wiiu hardware compared to Wii this is the number that would be more realistic than Brawl with a 100m userbase.

My prediction

SSB for WiiU= 6.2mil
SSB for 3DS= 4.5mil

you said it, look at the trend. You've been talking about a franchise that have been selling better with each iteration, no matter the installbase. N64 sold better than NGC, yet Smash Bros sold 2 million more copies. The facts are there in front of the people. but everybody looks what they want to.

I dont really believe trends can be broken down over a decade a part.  Nintendo games has always had a high attatch ratio so it is a given it will sell well.

Melee in general was just flat out better than the original which increased its overall numbers.  On the other hand Brawl is listed as the inferior version of the two but it was also highly anticipated with at the time the most popular console in the Wii.  Not only that, but the Wii was on the market for a lot longer than the GC giving it extended legs.

Smash Bros 4 is also highly anticipated but it doesnt have the same thing going for it with the WiiU compared to the Wii.  I tell you what I'll make a bet with you that Smash Bros 4 (On WiiU) will not outsell brawl because im fairly confident with this assumption.  Im not even entirely sure it can outsell melee at the moment.

SSB increased but it wont (unless we are talking about combine sales) this time, WiiU sales will be lower im afraid, i think people who say under 3mil sales lifetime on wiiu is smoking something cuz SSB is a huge franchise, it'll push HW sales but it'll sell no less than 3.5mil but it wont sell passed 8mil if wiiu is still doing terrible. TBH im interested in the handheld especially in japan! lets see how it does!

super smash bros will sell Wii U like crazy! Sony has helped Nintendo by releasing Battle Royal.

How much do you think it will sell on the WiiU?  It is fine with whatever you say.  I just want to hear your opinion.

U say that but install base dont mean anythng for this game! GCN 21mil~SSBM 7mil      Wii 100mil~ SSBB 11.8mil

i saw three polls here of which version is everybody getting, WiiU detroyed 3ds in the poll, the experience will be much much better, but hey you never kno right!? I hope both do well, im buying both dy 1. Actually  now thinking about it, 3ds  will need their owncopies and i have to buy 2 *.*

Does Killer Instinct count? That comes with every XB1, so it would probably beat SSB.
