What on earth could it be?

maybe it is from mistwalker

I'll believe it when I see it again. I want meltdown levels of Bayo 2 if it's big.

I'm betting it's Sonic's 3rd game, possibly a real Mario & Sonic crossover! Would explain why they didn't make a Mushroom Kingdom level for Lost World.

Devil May Cry 5?

i saw on neogaf that they are speculation it to be devils third since it says in the vein of bayonetta 2 which could mean that nintendo saved a hardcore action from getting cancelled by making it exclusive to their platform

You should clarify the fact it's a rumor, especially since it's from "gameblog", one of the worst french website...

Hope It's a good exclusive.

I hope is a good game at the end. A new RPG from mistwaker would be awesome!

I've been hoping that Nintendo would tap into Sega's IPs to get more exclusives like they did with Bayonetta. Possibly pay to have a new Skies of Arcadia, Jet Set Radio, Crazy Taxi, Nights or any number of other games made.
