Another thing to keep in mind for Skyward Sword sales is that when it launched on the Wii, it was right in the middle of the holiday season. This is in mid-July.
That, plus being on the Switch in its prime, as opposed to the Wii on its way out, I have every expectation of Skyward Sword HD surpassing the original Wii version. Just like Link's Awakening on the Switch ended up surpassing the original Game Boy version AND is just 570k units away from outselling the Game Boy + GB Color versions COMBINED!!! (I know those are worldwide sales and this is a thread about strictly Japanese sales, but it's still worth mentioning!)
Breath of the Wild and the Switch have truly done wonders for the series! It's popularity has skyrocketed to new heights!
