Day 1 and soon be ready for MK8D.

No.

Got it day 14. Its an impressive little thing and BOTW is phenomenal. No regrets

People who bought a WiiU are going to be the first people to buy the Switch.

Hell I'll be getting one this year even though the hardware isn't my cup of tea.

My wife pre-ordered it for me, so I've had mine since Launch Day.  In addition to Breath of the Wild on cartridge, I have 11 digital games already including I Am Setsuna, Shovel Knight:  Treasure Trove, Puyo Puyo Tetris.  I'm very happy with the system.  I have no regrets regarding my 2012 Wii U purchase mind you.  I've just been excited regarding the Switch since seeing the first trailer.  Being able to continue playing on it out of the house is a major plus side for me.

No, i can play Zelda on Wii U and i am not even interested in the new Zelda now. Its really hard to consider getting one right now, it needs more exclusives like Fatal Frame for me or a cheaper price.

I will get a Switch mini or Switch TX2 and skip the original model.

Not yet. I'll wait to see until there's plenty of Switch games I want first.

Of course not.

The switch is useless if you have a WiiU, until Mario odyssey.

I will maybe get one near Xmas 2018 if Ns got enough good games, especially fire emblem.
I wait a bit for a better model, it's nintendo after all.

Day one for me and I never looked back.
