You're certainly right about Zelda. Unless it's radically different in a way that appeals to a larger audience, I don't see it selling any higher than 7-8m. Mario Galaxy 2 will likely sell 8-9m like the first one. Still, there's a chance it could sell 10m with Galaxy 1 and NSMB Wii improving the "Mario" brand. Plus there's a larger userbase.

Honestly, this is a hard question to ask. It would be easy enough to make a new Mario Kart, New Super Mario Bros, and Wii Sports, but none of those are going to push system sales. Really there needs to be something innovative that appeals to new audiences.

A new Wii sports? For the rest I doubt that we will see many other new 10 million sellers from Nintendo .....Except a Pokemon game or another sequel of a 10 million seller;..

...that many people think Zelda Wii will sell over 10 million?

I know there were a few problems with Twilight Princess, but over-hype was still a problem as well. Please don't let it happen again. 10 million for a Zelda game is possible. Slightly, but possible if they really, really do it right with the help of Motion+. They really have to make it more action-involved. Theres no other way - and it needs to be engaging, and not incredibly easy. I will be extremely disappointed in Zelda Wii if it isn't revolved around combat enough, and it really feels like Miyamoto and Aonuma may not even be considering this. Will we ever be heard?

I don't think any of the big 3 titles next year will make it past 10 million. Metroid will sell about 2 million, Zelda Wii about 6-8 million. Super Mario Galaxy will probably make it to 8 million sometime.

No way Other M gets to 10m maybe 2m if its a fantastic game (I'm looking forward to it)

Mario Galaxy 2..Nah it probably won't sell as much as the first one tbh. (But it may be a better game).

Zelda..This has a shot if Nintendo nails something special with it such as it being a bridge title. I think at the very least it will outsell TP. But if I were a betting man I'd say no to these 3 core games hitting 10m+

Now NSMB will sell another 10m lol. Vitality could take off or it could bomb for all we know (which is not much). But how many 10m+ Sellers does Nintendo have on Wii already? For context how many 10m+ sellers do either PS3 or 360 have? between them 1? (Halo 3). Its an incredible feat to acheive, even though Nintendo is churning em out like its nothing its really quite incredible.

SMG2 and Metroid have no shot at 10 million, but I wouldn't say the same about Zelda. See, the problem is we know next to nothing about the upcoming game, which is why it still has a potential (though unlikely) shot. If they're able to design the game so it resonates with the expanded audience, 10 million shouldn't be a problem.

You may look at past sales of Zelda, especially TP, and imagine I'm crazy. However, TP also had a GC release, so the game actually totals to about 7mil. VGC has the original at 6.5 mil, and Ocarina at 7.6mil. To make 10mil, the new Zelda needs to improve its sales by around 50% over the older titles.

So far, the games that hit with the expanded audience manage this without trouble. NSMB Wii should outsell Mario 3 by over 50% (the only non-bundled Mario). Mario Kart Wii has already more than doubled the sales of the previous highest console version, and continues to sell well. Mario Party 8 will end up over tripling the sales of the original.

Really, the question is whether Zelda Wii is built to draw in new fans, or ends up catering to the same old. I'm not that optimistic about it (the DS games have me worried), but some believe the team can pull it off.

Try these:

Wii Visit - a travel sim. Think of the 'little USA' segment of Pilotwings 64 and add in sandbox cities. Two versions at least - Wii Travel: Europe and Wii: Travel USA. Get to explore the world - open ended like Endless Ocean, part educational, part just going Wow at stuff. I seriously think something very good and widely accessible could be made of this, especially if there's an SD card pack-in to hold all the data.

Wii History - same sort of thing, but in time. Basic mechanic is when you (the player, as your Mii) talk to someone else in the game you take over that character, take over their life. So if you talk to someone 50 years older than you you're going back 50 years in time. That way you can explore the whole of history one conversation at a time, skipping back and forth and up and down a family tree. Again, educational, accessible and potentially a lot of fun. Bring history alive in a way that's never been done before.

For now nothing, unless we get new info on Wii relax or whatever it's called.

The way i see it is that Zelda Wii will do 5 mil+, but no Zelda game has sold over 8 million so i cant see it doing above that. Also i see SMG2 doing very modest numbers, above 5 million but i don't think it'll compete with SMG numbers imo. However they seem to be announcing 10mil+ sellers each year(last year NSMB, the year before WSR), so we'll just wait and see

well consodering all the new IP's nintendo have introduced this gen they have something up their sleeve. Personally i can see a starfox this year along with the zeldas, pokemons and metroid. Again I dont think there will be anything this year on other consoles that will match the biggest selling nintendo game of this year in sales.

Yeah, that's more or less my line of thinking.

I must confess, though, I thought Ocarina of Time had broken the 10 million barrier. Outselling any previous Zelda would be an impressive feat, but not an impossible one.

I agree with these.   I figure SMG2 for 6m - less the the previous one since only the Nintendo Core will want it, the casuals have there Mario platformer fix with NSMBW and that'll last them until next gen.

Yes a Pokemon MMO would be awesome and could topple WoW.  

Wii Vitalty maybe but we have no idea really.

Other possibilities (aside from sequels to 10m games already out) - Nintendogs Wii.  Super Mario/Super Smash Bros Paintball.  Possibly an expanded audience Donkey Kong Country (the original sold 9.3m).  Maybe some reimagined Brain Age but I think this works better for DS.  And I'm going to have people scratching their heads with this one - Wii Music Plus with MW+, far better and far more music tracks and redone so people without any musical ability can still feel like they are making beautiful music.  There was a lot of genius in Wii Music but unless you had talent you wouldn't appreciate it, also it suffered greatly from Guitar Hero and Rockband.   GH & RB are on their way out and people would now be open to a new interpretation of the music genre.
