From Software is one of my favorite Jap Devs since SE is far up their own ...
I get why people like them for the Souls line, but I prefer the Armored Core Series myself.
If Capcom has to be bought, I think it should be a Japanese Multiplat dev before we even consider platform makers.
If not From
Sega
Atlus
Toei
Game Freak
Hudson
Funimation
Bandai Namco
Square Enix
Nintendo | Sony
Let's face it Sony and Nintendo both focus on their own IPs and NIntendo focuses even more on their succesful IPs, with the Exception of Megaman, a Multiplat dev would at least ensure the most IPs stay afloat, and SE would take them to mobile so even more people can enjoy Street Fighter, a series btw that I really doubt Nintendo would want competing with Smash. Sony would actually focus on Street Fighter (kind of tapped out on 4 imo) but regardless From or a multiplat like it would be the best option.
That is if Capcom was for sale.
