Go Nintendo - I don't know about this one. Doesn't seem like it's the real deal to me. I imagine the retailer has made a mistake with this listing, but we've seen things like this come true in the past. Just look at the Telltale Switch fiasco that went on for months until Telltale themselves confirmed.
That said, something just seems fishy about this listing overall. I wouldn't take this one too seriously until other retailers start sharing the same info.
Here's something worth pointing out. The retailer has since changed the listing. The removed the release date, but left the listing itself. That certainly seems to bode well when it comes to the validity of the listing!
