I mean Sony already kinda tried with Vita, Vita TV and Remote Play. Not exactly the same but it's there and now available on PC/MAC. The portability factor is basically you using your laptop to connect with your PS4 through Remote Play and all you need is an internet connection (and your DS4 with dongle or USB cable). AGAIN not the same but the idea is there and obviously Switch will be doing it more better.
MS has that whole thing Windows that's also kinda similar to remote play-ish. I actually don't know about it much so maybe someone could explain it better than me.
I don't think they will try and copy this unless it becomes Wii 2.0
I think Sony is pretty much done with portables after the Vita, which is a shames since the Vita if still a damn good handheld.
