Very very difficult to guess without knowing if a price increase is coming, and if any big unannounced games are this year.
After an insane launch it's slowed down a bit in the holidays to be reportedly slower than Switch 1. Will be interesting to see how Jan stacks up to Switch Jan 2018 and if it was just a holiday blip and will start outselling SW1 again.
Could really be anywhere from 15-20m at this point imo.
