MS + Valve should use Switch to go portable (with cross platform play).

If Steam wanted to take there business to portable markets they'd partner with Nvidia, as has been said.

I don't mean Steam or Games for Windows going to Switch. This is about putting their IPs on a portable system (untapped market), to boost playerbase, game/DLC sales and increase the number of active users for their own respective online services (and to hurt their nearest rival).

Valve, MS and Nvidia can't support a dedicated handheld by themselves.
