OK, I'm going to pretend that the thread title contains the words "on the PS3 or 360" (using 'best selling HD gamel would not work, because WoW has already sold more than it ever will) and shall ignore the edit that started by attempting to say this and then just ended up trolling the Wii.

No, I can't see anything beating it. GT5 certainly won't, not even if we limit CoD6 to just the sales of the 360 version

FFXIII won't even come close - either considering multiplat or single plat

GTA5 obviously will outsell it, but only if we include sales of the Wii version

Modern Warfare 3 will release on the PS4 and 720, so I can't see the PS360 versions of it selling very well

CoD7 won't outsell it

Halo reach is a bit of an unknown, it could end up topping CoD:MW2's 360 sales. Maybe

I'm not talking about platform specific, but thats an interesting angle to discuss if you want to. So if you think Halo Reach will outsell it on 360, thats interesting to discuss but not really what I meant.

Are you so sure GTA5 would outsell it including Wii? I dont think the Wii version will sell that much. And MW2 seems to be doubling what GTA4 did. I also think people are getting tired of GTA and that GTA4 was perceived as a let down. OTOH, GTA5 will have more consoles to sell into.

Also, no way MW3 will release on PS4/720. MW is a every 2 year series, and there's no way new consoles will be out in fall of 2011. 2012 is the absolute earliest for next gen HD comsoles and all signs point to 2013 actually imo.

Also, are we really sure all these Wii games are going to outsell COD6? COD6 will sell and sell and sell for the next 2 years. Given the initial shipment was perhaps around 20 million, I could see 25-30 million eventually happening. Of course, that would include the Wii version itself which is kinda not fair when exclusing Wii games lol. But then again the wii version probably wont sell more than a couple million, so if you exclude it you wont affect the numbers too much. But I still think it's fair to count, since we're only looking at games on the HD consoles, we can include the wii version since it's a subset. If that makes sense.

it won't sale 20 million, that's not how high profile games work.

GTA5 will.

GT5 will on PS3
Halo Reach might on 360.

Ahh, I was unsure if you were talking platform specific or not. 

As I said, I am fairly unsure what numbers reach will do

We shall have to wait and see with GTA5, but I think you're underestimating the Wii's software selling powers. MW2 does not have a chance of doubling GTA4. 

No chance of a 720 and/or PS4 in 2011 you say? Considering how much of an advantage MS got from releasing first this gen, they will certainly try to do it again next gen. A xbox 720 Halo game is currently being developed. This gen is approaching its end. I wouldnt be surprised if n 8th gen portable releases for Christmas 2010.

As for which Wii games will outsell CoD6, Wii Sports, Wii Play, Wii Fit, MK:Wii are all guarenteed, as are Nintendogs, Pokemon (diamond I think) and NSMB:DS. WSR, WF+ and NSMB:Wii all have a chance

I will probably get GT5 to go "wooo, ahhh" but I'm not optimistic on it selling more than 20 million, not GTA5, and certainly not Halo Reach.

With combined sells (360 + ps3) of course. In an speciffic console I think answer still is yes but I`m not pretty sure, It ll be hard to reach Halo 3 =P in 360 and GTA V in ps3

Sims 2 is the biggest ever.

Communist hater - I'm pretty sure WoW has outsold sims 2.

Although Sims 2 + sales of sims 2 expansion packs > WoW + Wow expansion packs

Although Wow revenue >>> sims 2 revenue
