Personally, I don't feel like the system offers good value at that combined price point. Paywall'd online (eventually), 330 for bare bones system without game, around seventy Eurodollars for games, hidden cost due to the sparse internal memory practically necessitating SD card purchase in the middle to long run, luxurious prices for accessories. Combine that with a so-so lineup and spotty release calendar, which was the thing that really bent Nintendo over the barrel with the WiiU and 3DS (and required some desperate measures to rectify). Plus, the online service is entirely unproven and lacks appeal. The way they outsource much of the online goodies to the smartphone app seems fishy, and the fact that the entire thing isn't even up and running yet makes me fear what is to come. Battery life is at the low end, but that's kinda unavoidable I guess. Still disappointing.
So, from my perspective, it's a flawed, but somewhat intriguing handheld, a flawed and pretty unexciting home console, and I do not expect it to have much draw outside the faithful. That'd put it around GameCube or WiiU levels of sales, I guess. At least I feel like the momentum just isn't there, barring any further hype building until release (Treehouse, further PR/announcements, etc).
I'd be really happy to be proven wrong though, being a Nintendo fan at heart and all. There's always the end of year period in 2017, where they could potentially gain some traction with a stable release library, a bundle or two, plus the new Mario and whatnot. Plus a new firmware update that addresses any previous complaints, and then some. I guess. If MS and Sony leave them alone. And if word of mouth is good. And if they trickle out teasers and games and whatnot to keep switch in the hearts and minds of gamers. And so on. Hrm.
So, anyways, GameCube or WiiU, or in between the two for me. Probably far closer to the latter than the former. Pessimism, yay!
