How much will Super Smash Bros. for Wii U sell in the first week in the US?

I'm trying to compare it to like Halo MCC.. which sold what? 600K FW. Both are pretty big system sellers. Although that number may be well off. I want to say it won't do more than Halo FW numbers whatever that really is.

I'm going with 490K FW NA, may prove me wrong. Plus Halo had a lot of negative reception for online...

it will do a lot more than a collection. 1m+

Would you have said the same about Mario Kart?

This is US, where XB1 has a big userbase advantage that buys Halo like crack.
