Pretty decent for a remaster.
Recent Zelda US 1st weeks, from VGC:
Ocarina of Time 3D: 156k
Skyward Sword: 604k
The Wind Waker HD: 128k
A Link Between Worlds: 262k
Majora's Mask 3D: 353k
Triforce Heroes: 70k
I guess this shows how Twilight Princess is the most popular Zelda game nowadays, if a remaster on a system with a low install-base as WiiU can get to two/thirds of the sales Skyward Sword did on a system with ten times the base, which was an original release to boot. Though I wonder what the amiibo did for it.
TPHD is apparently second only to SS, but obviously I get that OoT3D and WWHD were released earlier into their system's lifetime. TPHD did beat both A Link Between Worlds, an original game no less, and Majora's Mask 3D. Makes me curious for Zelda U's opening.
I guess this is also another nail into the coffin of the pre-order numbers here, because that was like what double? Anyway that's just an indicator anyway.
If these numbers are correct of course.
EDIT: Bonus: Hyrule Warriors: 129k
