I think if not a full blown partnership, MS and Nintendo should consider a "non-aggression pact" as it were where they help each other a bit.
MS gives the Switch a Halo game or two, Rare games for Virtual Console, in return XBox/Windows PC maybe receives some older Metroid Prime titles in 4K.
Nintendo gets the better deal because they have the more valuable franchises (Halo for Metroid is a win for Nintendo), MS gets some nice PR. They're both getting kinda fucked by Sony IMO with Sony pushing devs into exclusivity deals, so they should strike back a bit.
