Considering they are losing space to Smartphones and Switch doesn't seem like it will correct that I expect them to not cross 50M, but I'm sure they can make more money due to higher prices on SW.
On the droughts though, they were having difficulties releasing PS3 level graphics 6 years after the other companies... so even unifying if they really are close to X1 capabilities they will have even more issues releasing games to satisfy this, so I'm not sure you'll get luck to see it going over 100M.
And most of your points were pretty generic that could be made to any of the 3 or even new entrants to justify any sale you decide.

Mr Puggsly: "Hehe, I said good profit. You said big profit. Frankly, not losing money is what I meant by good. Don't get hung up on semantics"
