Zelda, Mario, Splatoon, and possibly Xenoblade in the first 10 months is quite good. However, sales will be lacking during the empty months because of the price. Price cut will take effect in..... January 2018. Mario, along with Pokemon(presumably) will make the switch sell insanely during the holiday season, regardless of the price.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
