The ironic thing is that since this thread has been made, Microsoft has gone third party. I can play games like Cuphead and Ori on the Switch now. Add Minecraft on top of that which is the best selling game in the 21st century. Microsoft just released Minecraft Dungeons for the Switch and I hear it's selling pretty well. Microsoft may actually be Switch's best third party partner. No doubt they are at least in the top 5.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
