So this is out now. I don't have the file, but there are some interesting things that have been revealed. Info here: http://filb.de/2195
Local events don't appear to be region-locked. filb.de got the Inkay on a German game, and Masuda himself got it on a game in his French 2DS (which due to region-locking would necessarily be a European game).
The filb.de article also shows off the OT, ID, Ability, Nature (or at least a potential one), Ribbon, met location, distribution text, and German Wonder Card (although I'm guessing all Wonder Cards will be the same for all events now).
