It’s somewhat misleading. It’s not providing the additional background information, and it leads the headline with the claim (not that Nintendo is making a claim).
I don’t think it’s a bad headline. It’d be hard to include all the information in the headline. But if someone only reads the headline (something like 73% of people), they could end up with a mistaken conclusion. And those people will have been lead in that direction (so, mislead).
To clarify, I don’t think the writers did anything wrong. The headline will be misleading because Nintendo’s being somewhat misleading.
I don’t know how much the headline could be improved, if at all.
Or if they can’t quote “officially”, they could quote “only”. Which could arguably be more clickbaity, but also clue in a casual reader that there’s more to what Nintendo officially says.
