Considering how many where saying "I won't buy a Wii U just to play Bayo 2!" and having or planning to buy a Switch, I'd say it will sell substantially better than Bayo 2 on the Wii U. Also, unlike for the first game, this is now a pretty well-known franchise.
So my prediction is:
260k FW, 1.2M LT
And for Bayonetta 3:
360k FW
1.8M LT
