are there any problem if i gonna buy my switch from japan?

YEEEEEEEAAAAAAAAAAAHHHHHHHHHHHHHH


edit: as for the dock, no doubt 3rd party ones will appear later in the future, bar from few chips that isn't recognized most of them can be purchase from farnell or any other shop. then figuring out which replacement can be used, design the circuitry, ordering your own pcb and viola 3rd party dock. although I doubt it will be faaar cheaper unless they don't come with the usb power adapter
