Those things will come, I've owned all handhelds but the only Nintendo I've never owned is a SNES (blame the parents). I've decided to get one, I've put my "New" 3DS up for sale and I'm going to try and grab one when I'm on my honeymoon. You just can't beat Nintendo on their flagship products.. I'd rather a Nintendo for 1 Zelda/Mario game.. they are THAT good!
I dont own a PS4 or XO simply because there is not enough there to grab me, the games I'd find appealing are hidden away amongst the Tripple A's. Nintendo has got on board and it's coming across as a major part of the eco system they're creating. I'll be honest and say the UI is drastically different from what they've done and it threw me when I booted it up, but I can see it only as a positive as the W/U interface was just oblique and too complicated.
They're on a great path, I just hope developers now realise and release titles, rather than Another Rayman port and generic titles released 5 years ago.
