Agreed. With Wii U and Vita sales being so bad, and 3DS doing well but far behind DS or GBA, I was concerned that the gaming market was shrinking again.
That was definitely misguided. The Wii U is just a bad console, and Nintendo games just don't appeal to many outside of kids and their niche of diehard fans as people want to play shooters, sports games, racers, GTA/AC type games and WRPGs primarily these days. Not platformers and other games with cartoon graphics. The Vita doesn't sell as there just isn't a huge market for a portable aimed at adults as most just want to game on their big screens or PCs and just dick around on their phones/tablets when out and about. 3DS still sells well to kids/parents, but that market is down some as so many are just playing Minecraft and what not on cheap tablets, handed down smartphones etc.
So I'm happy that both the PS4 and X1 are selling well and showing that there is still a big market of core gamers who want to play traditional games, with traditional controls on the big screen. Yes, I'm happy Sony is doing a bit better as I like their direction more, want to see more AAA Japanese games etc. But I'm happy MS is doing well too as it's better for us gamers having at least two strong contenders in the market. And it's nice having Nintendo around too doing something different for people into what they do and less so what Sony and MS focus on.
