Jordanv78 : I'll admit you have a point but I think the Wii did so well because it was a hit with casual gamers and that was one of the reasons they didn't need to have as much 3rd party support with the Wii. Now Nintendo is losing that demographic to sony and microsoft because they have much more variety. And there have still been 3rd party games that did well, like Resident Evil, Monster Hunter, Skylanders, Just Dance (and those last two are clearly intended mainly for casual audiences) for a few examples.
But since Nintendo no longer has that market cornered they need to find ways to appeal to gamers and more 3rd party support I think is key (as well as stronger launch lineups though no console has done well in that regard) Like Eirinn I'm not saying it will make Nintendo suddenly surpass sony or microsoft but it's to still stay competetive in terms of home consoles.
I would actually argue that the Wii U is not that cheap considering it's age. Yes it's still the cheapest of the three but it's not by much compared to the PS4 and XB1 considering the specs (granted that can vary from area to area), and the gamepad, which is what makes the console itself different isn't going to convince most people as it isn't utilised enough to justify the price it adds, another reason why it's not going to seem very attractive to a lot of people who aren't nintendo veterans. Even big games like smash bros, can only do so much in terms of sales. Nintendo should still try to do things a bit differently, but just being different doesn't automatically mean it's good. They have to really utilise what makes the console different as well (which they haven't really for the most part, especially early on), and not do it on the expense of things like no 3rd party support at all. It's hindering sales more than it's helping really. In that case the gamepad would've been better of as an optional add on instead.
As for the fanboys. The Xbox 360 had a lot of "fanboys" and outsold the PS3, yet a lot of people didn't really hesitate on jumping on the PS4 in stead this console generation. I mean same goes if you compares the sales of the original Wii and the Wii U. Unless it's one of those exceptions where someone will buy a single console just for a single exclusive (and those people are far from casual gamers and make up a pretty small part of buyers) I'm pretty sure they can be swayed.
But this is only what I think and you don't seem to see it in the same way I do.
Eirinn : Well that's what I was referring to when I said "keeping high quality". Unfortunately nintendo releases so far like Pokemon Shuffle have been loaded with micro transactions but they've also mostly been free so that's probably part of the reason. I feel that Nintendo could have the opportunity to lead the way for mobile gaming in terms of improving quality and make it be taken more seriously by hardcore gamers, though wheter they actually do that if they start to focus on mobile gaming seems questionable either way they'd likely make a ton of money as there will always be people willing to spend huge amounts of money.
