Personally I think the PS3 version will eventually sell more, but not this year.

What I find funnier is the number of people who think MGS4 will sell the most is higher than the number who think Mario Kart will.

Personally I think it will end up with Wii Fit 1st, although I can understand peoples arguments that it might not.

but then Mario Kart will probably be second despite so few voting for it.
Here is my guess of the order of those titles.

1. Wii Fit
2. Mario Kart
3/4. Smash Bros ~ GTAIV (360)
5. GTAIV (PS3)
6. MGS4

MGS4 is pretty much destined to be in last place, even if those hoping for phenomenal sales where it passes GTAIV (PS3) are correct will mean it is in 4th or 5th.

I am pretty sure I have the three Nintendo titles in the correct order, although we have yet to see Smash in Europe so It could stay ahead of Mario Kart.
GTAIV is the tough one for me as I don't know how it's legs will pan out yet, the PS3 version is unlikely to be higher than 5th, at best 4th by January but the 360 version might be able to outsell Kart or Smash or both.... so all three of those titles might be close.

Well. maybe some people opinions will change after MGS4 release + 80Gb model. =)
But that 1 month away or 2 month for NPD data. =]

I agree with TWRoO, i voted wii fit basicaly becasue I'm not convinced GTA will have the legs to hold up consistant sales throughout the year where as wii fit has legs that could bring it to the level of wii play

The 360 version is already pulling away, lead increasing from 0.7m to 1.1m gap, increasing the ratio from 1.27 to 1.33 based on VGChartz data. NA its already very near 2:1. And EU+Other sales are already almost equal. To me it was just wishful thinking and cheerleading on the PS3 members parts (very apparent in this very thread).

yeah since 1974, ahhhh the good old days of the xbox

actually, WiiFit is going to be the best selling. seriously. everyone's mum is going to want one.

I give no chance to the PS3 version to outsell the 360 any time in the future. The ratio by the end of the month will be 2.5:1 in NA and 1:1 in Europe...

Crazzy: You might not have had the news yet but it's very unlikely the PS3 will see a pricecut this year.

Sony announced a shipment target of 10 million for the FY 2008. Since they'll probably make that target quite easily, they won't need a pricecut and therefore won't do one.

Basically people aren't thinking of sales, but rather voting for the game they like the most on the system they like the most. Heck, there are almost as many people thinking MGS4 actually stands a chance. -_-
