This is an exclusive to Best Buy in Canada so it would probably be an exclusive to Best Buy in the US as well.
As far as I know Best Buy US doesn't ship out of the country but if they do get it then there would probably be an HDN group buy for it.
Admittedly lot better-looking than the steelbook for the first film releasing at the same time . . . will go fine with the UK steelbook for the first film (a steelbook that I believe is still not OOP/OOS after almost four years) . . . although would have preferred artwork reversed with front image matching better HTTYD I:-
As image stands plenty of space for the title although clunky titles such as on the UK steel are not always a plus in the steelbook's favour.
