Played it tonight. Very very nice, my kids love it.
I'll buy a Switch in a year once there's more games and they have the kinks worked out. If I feel like playing Breath again, I'll get it second hand.

To my untrained eyes, the Wii U version seems perfectly fine.
Though so far the atmosphere isn't as deep as the Zelda games have done in the past.
Though I thought Skyward Sword was just annoying so this is a relief.
