You didn't even say how the fusion is gonna work, like are handheld and console components gonna be sold together so each unit sold counts both or sold seperately so each handheld and console sales are seperate.  This thread is pointless without some context.

You should first wait for any fusion announcement and then wait to know what exactly is the fusion consoles.

Wow, people really missed the mark huh? I dont know enough about the Fusion or how Nintendo plans on representing/marketting so any guess on my part should be taken with a huge grain of salt. If it is some handhled/docking/unified platform thingy than 80m "should" be a resonable estimate.

From what I understand of the Fusion, it is supposed to be basically a portable home console. Something you can play on the go, as well as hook up in your living room and play. Essentially, one platform that is supposed to unify their two traditional platform. Honestly, if that is the case, its going to be a pretty hard sell for me. I generally don't do handheld gaming, and I especially don't do mobile gaming.
If Nintendo's aim for its next console is something that will being phasing out the home console side of things, then I basically don't want it. I'm not a big pokemon fan, I don't care for the casual titles the ds/3ds offer, and of the few amazing titles that do generally come along for a handheld, nearly all the rest are shovelware. If Nintendo's big plan is something along the lines of what the fusion seems to be, I'm pretty damn scared for their future.

I'd wait until it's at least announced before making a prediction.

The Fusion is two consoles doe. The rumor doesn't imply at all (besides the name) that there is a hybrid console, it talks about both a handheld and a home console . Also the rumor is one of the worst rumors that has gained traction I have ever read.

Anyway, I do think Nintendo's next console will break 80 million, even if it's not a hybrid.

I doubt it will be that exactly.

It will be the handheld chip on both devices, but you'll have to buy seperate devices to play on your TV. 

Same deal as Vita + Vita TV ... you can't just hook up your Vita to your TV, you have to buy a Vita TV for that. 

Except I think in Nintendo's case, the console version will be more powerful, they could just literally even just use 2x-3x the CPU/GPU cores. Mobile parts are small, power efficient, and usually scale in cost very nicely, making a "stackable" console variant very easy to do. 

Probably the most premature thread on VGC I ever read

Lol, too many "ifs" and "buts". The bottom line though...

The software output for the gamecube was amazing but here it sits at 22m

Third party support and desire from gamers to play third party content on the system is the only thing getting you 30m+ in hardware sales and there's nothing in the fusion concept to secure that.

If this gen was a Fusion platform you'd have roughly 55 million portables and 10 million consoles sold through already. 

So ... the portable aspect of it will likely carry the bulk of the sales, whatever they sell with the home version will likely just be gravy/icing on the cake.
