Nintendo not making a line of remasters for Wii U was one of their biggest missed opportunities to expand their line-up in a really cheap and easy manner, seeing as WWHD apparently only took 6 months to make IIRC.
Hopefully Tantalus is hired to be Nintendo's Bluepoint and makes many remasters on NX where their original devs would be hard to reach for them (busy or virtually non-existent), like Xenoblade Chronicles Wii and The Last Story for example. They can get other devs to do other remasters like Bee Tribe to port again Bayo 1 and this time Bayo 2 to NX (they actually helped out on Bayo 2's development also).
Especially with Bayonetta's inclusion in Smash and if she will be in Smash 5 on NX, this could be a great idea. I feel her inclusion should've been planned from the start which would've been BRILLIANT marketing for Bayo 1&2's launch on Wii U.
Also I wonder how Tantalus are handling remastering a Japanese-developed game (as they're Australian), I think it's their first ever IIRC. They must be using the English localization as the base? Same as what Monster used for Xenoblade 3D I guess.
