3DS: Yes. One, since OoT3D released. Technically I have two, but the other's an SE that remains sealed. I guess that means you can still put in "2" then though.
WiiU: Yes. One, since launch day.
Switch: No. I don't really want it for the hardware, but I know I'll just have to suck it up when good games come, so even if I want to say no period, you can put in "Not yet".
