There was a time when things were created to either enhance gameplay or make something more accessible / easy. The first six things you mentioned were created with that in mind. Personally, I see no reason to take a photo of myself, yell at my DS to get to the next level, carry around a larger handheld system or view ANYTHING, let alone a videogame, in 3D. Not only that, but I also don't want to be flailing my arms around or jumping up and down.
Nintendo created a divide in the gaming industry. They lured more casual gamers who demand and enjoy easy gaming environments with lots of flashy things to accompany their system. The more things it does, the better the investment. Because of that, Nintendo has forced Sony to create [steal] Playstation Move and Microsoft to develop Natal. Gaming and development is no longer about gameplay and how to deliver a more expansive world with a complex physics engine and an interesting art style, it's about how we're going to suck in more people to buy our systems. The entire industry has made a huge shift towards becoming more commercial and the products are suffering.
So yes, it is a bad thing that Nintendo is trying something "new."
It's not so serious. This was only for a bit of fun.
