Just because some in the industry are having a bad time and changing does not mean anything.
"But Microsoft" Microsoft what, no one cares.
Sony Is still doing good, their games are selling and so are their consoles.
Japanese Third parties are still chugging along and doing great.
Square Enix and Final Fantasy are still the top dog when it comes to JRPGs. All this without Nintendo.
Just because Nintendo found some success does not mean he won, or that others are doing bad.

Sony and Microsoft are bot going third party.
The only ting that could make this more of a win is Square Enix dying next.
