They're into a niche market now.
I bought a couple gamecubes for the kids back then. And 4 or 5 gameboys.
My grand daughter still plays her DS, but she barely played with the Wii. I think I have 3 games she hasn't opened yet because the thing isn't hooked to her tv. I put a playstation 2 there instead. Why do those nunchuks things need batteries? It's like being back to the dark ages of the original gameboy advance.
I don't consider the 3DS to be an upgrade, so I bought her a tablet instead.
Nintendo used to make products that you could buy blindly for your kids. Now it's just some gimmick based alternate platform for those who are still hooked on Nintendo's franchises.
For kids, you might as buy a PS3 or a 360. It's cheaper and all they want to play is Minecraft.
