Release date for the European release has been confirmed but a more reasonable pre-order price is still yet to rise. It'd be great if it was £22-25 (it's below $40 basically) like Splatoon and Yoshi but who knows, maybe it will too.
Definitely interested in checking out this game for the right price.
