Just in case this needs reiterating, everything here should be considered a rumor at this point. It wouldn’t be that difficult to whip up a fake sales listing and post it online to get rumors going. I’m not saying that the original poster did that, just that someone could have. Then again, if you’re going to start a rumor about an unannounced Switch game, this would certainly be an odd one to hitch your mischievous wagon to. If you really wanted to cause some chaos, you’d probably claim either Assassin’s Creed: Origins or, more believably, Black Flag, were heading to the Switch.
