I did post about this in both the February Downloads and OT as it went up, but nobody seemed interested. :\
Certainly at midnight in Europe it went up for €59.99 and then at midnight in the UK it went up for £49.99. It weighed in at 1410mb and took about an hour to download/install.
My guess is that was an automatic system and if it's not there now, someone realised and took it down.
It's still there now (search for it, don't expect a Nintendo banner) and the problem with retail copies was the packaging. Legal stuff perhaps.
