Is Nintendo finally expanding its market past kiddies? Don't get me wrong, it has a good number of games marketed for older people, but it seems like all they want to talk about is stuff like Mario Bros. and Legend of Zelda while shunting Metroid and Fire Emblem under the rug. Doesn't help that they're basically "kiddifying" Fire Emblem, either.
This is a good thing for Nintendo, and it's one that I've been waiting for.
Eh, I'll probably be getting one anyway so I don't this changes my mind, I'm already super pumped for Legend of Zelda: Breath of the Wild
But yes, this is extremely exciting, this is honestly the most interesting gaming related news I've heard in a fair while (since Skyrim SE was announced I guess), portable full-on gaming is pretty awesome.
It's more likely that they wont confirm it being on the switch until after the special edition is released for the other consoles (that is if it is on the switch), so that they can get people's money from that instead of having a bunch of people wait until next year to give them their money. Instead they'll maybe get to lots of money.
Also just becuase they haven't confirmed it doesn't mean they faked the footage. For all we know they could have thrown together a version to work just for that trailer to emphasis the 3rd party support since most people will recognise Skyrim.
