Using Wii Shop Channel rankings from the top American Wii markets -- US, Canada, Mexico, Brazil, Colombia -- along with historical sales data calculated from Nintendo Channel usage data, we can exclusively reveal to you today the sales for the first day for the hottest WiiWare title to date:

Day 1 sales for the Americas:

Mega Man 9 (WiiWare, Capcom, 1,000 points):  60,000

Yes, that's right.  In one day Mega Man 9 outsold all but six WiiWare titles' lifetime totals.  In one day it outsold Strong Bad Episode's 1 lifetime sales from over a month.  For the full week it could surpass the lifetime sales of every WiiWare title -- and most Virtual Console titles, as well.

Needless to say, this is a pretty successful debut.  We'll bring you full week sales next week, look out for the first-day sales of the XBLA version when it launches next Wednesday.

The other titles released were Plattchen Twist 'n' Paint (WiiWare, Bplus, 1,000 points), Super Dodge Ball (NES, Aksys Games, 500 points), and Vectorman (Sega Genesis, Sega, 800 points), and none of them had enough first-day sales to crack the top 20 (less than 1,000, probably far less).

Stay tuned for the full weekly charts later this week!
