I think the Switch will probably click for me in the next year or so when I get more games I want for it. I had originally thought that it could possibly replace the PS4 and PC for certain third party games due to the portability aspect but it just didn't seem to turn out that way, I still buy most of those games elsewhere. For me it will be another exclusive only machine but probably better placed in the industry to get the extra exclusives to make it worthwhile unlike the Wii U.
One thing I would like to see is better pricing on digital games. Obviously not just a Switch thing as the other consoles are just as bad but I feel like they have such good sales quite often that it offsets it a bit. There is no way I'm paying £50+ for a game, especially a digital one (and a re-release no less, bloody One Piece!).
