Knowing Nintendo, we'll probably get some new IP's for the Switch. What I'm wondering however is what people are anticipating.
The only new IP we currently have is ARMS, which is...rather interesting to say the least. Seeing their past IP's, I think we should expect another 'fresh' IP to arrive with some sort of competitive scene. We currently have 2 active fighting IP's, so perhaps we may see an RPG be developed for the Switch as well.
Also, I know these aren't new IP's, but I really hope Ever Oasis and Wonderful 101 get sequels. They're deserving of one honestly, as they're fairly solid series.
