@ShadowlinkThe 3DS sold fine but it was nothing compared to 150 million of the DS. Imagine if your yearly salary dropped from 150K to 60K, I don't think you'd be too happy about that!
And I do think Nintendo has been screwing up recently, since the mid-life cycle of the Wii basically. Heck the Switch is probably a screw-up too, I can't imagine that thing being easy to port too so I doubt it will fix Nintendo's 3rd party support problems, for me personally I'm really hyped to have that big beautiful screen on the go, and Nintendo-developed games that use normal controls instead of motion controls, but I'm not sure the average gamer is going to be swayed from their Xbox's and PCs if this thing cost $300+ and doesn't play Battlefield One, Mass Effect Andromeda, Red Red 2, etc.
I love the idea behind the Switch, but I've always been all about portable gaming, so I wouldn't be surprised if the thing flops in the western markets where people just want to play games at home on their couch (or at their desk if they prefer PC).
