I don't think they are trying to kill it, they are just stupid. Nintendo thinks the 3DS is doing perfect. They think the 3DS is selling well enough to not get constant support. And, because of this, they moved on to supporting the Wii U; an already dead, hopeless console that has no life ahead of it. (Even though Nintendo thinks so.)
The answer is, Nintendo is stupid.
