Huge big brain move, Sony and the CMA was trying to lil bro Nintendo as not really being something COD would be on because it's "too violent" aka they not really in the mature gaming space.
Only for MS, steam and Nintendo to all hammer out 10 year deals in no time.
This tells me that steam, and Nintendo have good relationships with MS.
Nintendo usually stays out of this kinda of thing. They didn't have to do a deal of any kind.
But then doing so either means they are in favor of MS or they truly don't care.... Or they really still just don't like Sony lol.
I think it's a bit of all 3 tbh
