Now that I think about it. If this happens they're either going to have to compress 7GB worth of data to fit it in the 16GB standard card or leave it as is/improve it on a 32GB card. Possibility that they'll supply the Japanese voice acting aswell?
I imagine they'll go with a 32GB card. If the game outputs at 1080p and Switch has better specs than Wii U (including more RAM), I'm guessing we might see higher quality textures that use up even more space.
The juiciest news there is that Pikmin is supposedly a reboot. Wonder what that means?
LKD's follow-up tweets made it sound like the game, at the very least, won't be marketed as Pikmin 4 so that it's seen as a clean start. I believe she wasn't sure if internally it was actually a proper "reboot."
My guess is that they think sales potential could be hurt by calling it Pikmin 4, which could make people wonder if they need to play the previous games. Plus, Pikmin 3 already featured 7 Pikmin types and 3 playable characters, an increase from Pikmin 2, which itself was an increase from Pikmin 1. Seems like the games were getting more and more complicated and full. They might want to focus it this time, rather than adding more again.
