I think it will be. I expect COD5 to surpass 1million.

cod5 will pass 1,2 million but conduit will only do 500.000

I doubt it...

The system sells like crazy reguardless of games...And the few games that helped the sales are nintendo made.
As far as COD5...I don't think it will do bad as Wii has a large userbase, but I don't expect it to beat the ps360 version in sales. COD4 was all about online and great visuals... both of which Wii struggles with.

To the untrained eye, they seem similar...

No (The wii sells itself)

750k

Very few games are really system sellers, and the only game on the horizon for any platform that I can see really moving systems is Wii Sports: Resort mainly because of its direct association with Wii MotionPlus.

The sales of The Conduit will largely depend on how high of quality it really turns out, and how well it is marketed. If it ends up being an above average shooter, and is marketed as heavily as a game like Haze was, I could see it breaking the 1 million barrier.

every well known multiplat so far has done well so far on the Wii so COD5 will more than hold it's own - conduit is will do okay but not as well, depends on advertising.

Conduit will attract some gamers to Wii..So make your own sumptions

It all depends on how well the controls are done. If COD5 can match RE4 in controls, it could sell really well.

I don't think it's well known enough, or will be advertised enough to be a system seller. Wii doesn't need a system seller anyway so it's not a big deal.
