The race is on to score our #MK8 Limited Edition Bundle exclusive to #NintendoWorld! Pre-orders start now!
Seems to be the same as the EU LE : you get the Blue Shell figure. Obviously, it's NA-only since... well... the only Nintendo World (besides the one at NoA HQ) is in New York.
Launch even too :
Join #NintendoWorld on 5/29 for the early launch of #MK8 from 8pm-12 midnight! Visit nintendoworldstore.com for updates from our pit crew.
