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

[Spade]

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...
