Xenoblade 1 sold 1.5M+ if you include the New 3DS Version, the problem with this game was the localization, it was hard to find and was the 3rd wii's most downloaded ISO for people with a hacked console.
XCX had the poor Wii U system :/
I don't know if anyone noticed, but Xenoblade 2 special edition had been in the top 10 seller on all amazons for a long time after they announce the release date, and continues in the top 100 sellers until now.
Amazon USA: #56 (Special Edition)
Amazon GER: #64 (Special Edition)
Amazon CA: #64 (Normal Edition)
I predict 1m+ the first week, and 3m+ for lifetime.
