I guess the thread name can change now? Nintendo Switch revealed or something like that
Went and did just that!
So... the name sucks. When I say it, it sounds like I'm saying "Nintendo's Witch".
As far as the concept, it is hardly revolutionary but it is a safe and easy to comprehend device. Unlike the Wii U which initially was thought to be a Wii accessory and then had trouble getting people onboard because it was difficult for people to see why it was a novel idea (and TBH it wasn't).
As a home console, I don't think it will be another Wii U. Nintendo games will be the main draw, hardware will be a step below Xbox One and PS4.
As a handheld, it could succeed but the main things will be interface, battery and online ecosystem. Also, I feel it will be competing with the mobile market and the 3DS.
I personally feel burnt by the Wii U and will not be getting the Switch. I will continue to enjoy 3DS, will buy some more Wii U games and will eventually get a PS4.
