Well, as I said and many others here, there is still much to learn and I still think Nintendo is holding many interesting things about the Switch behind the curtain.But since the Wii, people grew accustomed to the idea that unless Nintendo comes up with a strange fun new way to play and its not a handheld, its going to fail(or not be as successful).I think you dont need to look no further than the PS4.For all te talk about power and all, compared to a high end PC, PS4 is nothing incredible.It plays games normally, has a normal controller, and even have a paywall for multiplayer, which I find ridiculous.But it succeded.Why?Because of a string of oportunities and right decisions.I think the same can be applied to Nintendo.Having a much more atractive lineup of games than the other two, if it makes the right decisions, and be active on getting deals, on marketing and such, i dont see why it dosent stand a chance at being very successful.
Nintendo is not Sony. Sony has a (well deserved) reputation with the "dude bros/jock gamer" crowd, Nintendo has a very poor reputation with that crowd.
Plus Sony worked their *ass* off to make sure the Playstation 3 recovered and finished very strong. Nintendo just let the Wii U die on a whimper.
There is still a market for a high end home game console, but for a portable? Eh. That's going to be a tougher sell in this day and age where kids have tablets from very young ages.
