Didn't find his sources he was talking about but so guess you'll have to take a listen yourself. Point is that Bayonetta 1,2 and 3 and also Astral Chain have all sold over a million copies on Switch.
This is damn good since some of my favorite IPs of all time can get a sequel.
The relationship between Ninty and Plat is reason enough for me to get a Switch 2 =)
