Is it sold out? No. If you want one, it should be be that hard to find one. Check your stores online like Walmart, Target..etc. They show you if they are in stock in your area.
For what I heard it's sold out online, but apparently it's possible to find a console on retails. I don't live in the U.S so I'm saying this things based on internet comments. Some people said they can't find one and some others said they were able to find it. That's why it's confusing.
