Well, gaming communities (which are not too technical) seem to be hyped, but tech communities laugh at the thing already(because they don't fall for the hype and examine the thing in detail). Here on gtatemp, a place mainly for Nintendo handheld fans, it is obvious what most will pick at the poll... Don't get me wrong, i am a Nintendo handheld fan as well, though the 3DS wasn't that great to be honest, in comparison to the original DS. And the 3D was indeed a gimmick, if it was so succesful Nintendo would have kept it.
In my opinion, now we have yet another gimmick. The trailer seems cool, but reality will be much worse. Make no mistake, those weren't real games running on the system you saw, those were edited scenes...
When i heard about the NX, i was very hyped because i was expecting them to release an upgraded Wii U, with the tablet sold separately and being able to receive the same cartiridges as the main console to play on the go at a lower detail level. That would have made the most sense, and it would be quite feasible with the tech we have now, if they had chosen to go the AMD route. AMD will have ARM apus very soon, and those could be changed for jaguar-based apus for the main dock, thus making the NX competitive with the PS4Pro on the home front while retaining a handheld option. They could just include both executables in the same cartiridge. With some creative libraries, this would have been totally possible.
It seems Nvidia was DESPERATE to get the sale (initial rumours indicated Nintendo would go the AMD route), so they sold their Tegra to Nintendo at a better price(near cost) + offered to make all the libraries themselves (as we can see from their blogpost). Nintendo being the greedy bstards they are, couldn't say no to this, and the result will be another failed project, the Wii U Version 2.0 .
Why?
1) It will cost near the other home consoles, while being quite behind in terms of power. This is a huge deal. In the current market (which is already hard for consoles in general and favours general purpose devices more), people want to get the best bang for their buck. If you show them a Nintendo console which costs the same amount and has similary priced games, but all the ports are of lower quality and the only exclusives are Mario and Zelda(which looks like a fail to me, btw, not hyped at all, seems quite empty for such an open world), people will prefer to get the PS4Pro or the Scorpio.
2) It will totally lose the handheld market. People bought handhelds because they were cheap, had cheap games, lasted long on battery, and were kid friendly. This is not kid friendly, this will be easy to break, ruin the screen, or lose accesories. And it is too expensive for that. Parents will buy cheap chinese tablets for their kids to play Mario runner on. They won't pay 300+60 for the console and a single game, only to see it broken by their 10 year old kid a day later. Forget about it. Not to mention that this is too big for kids. And it doesn't really fit your pocket.
3) People seem to freak out about Skyrim on the go. I did initially too. But having read some insider info yesterday, especially regarding rumoured memory bandwidth, it seems the Switch is 1/3 the power of the Xbox One. Which positions it around 2x the power of the Wii U. It seems the Skyrim version they showcased IS the Special Edition(remaster), BUT with the effects significantly reduced(that is why i initially thought it was the normal edition). While games will still be portable on it, i don't think most devs will bother, unless it achieves a huge fanbase, which seems unlikely due to its price. It will create another chicken and egg problem, devs won't create games because there won't be a big install base and players won't buy it because there won't be enough games.
DEFINITELY NOT A DAY 1 PURCHASE. Remember, people were hyped for the Wii U too initially, and initial sales were quite strong. Look how that turned out. Don't fall for the hype.
