Maybe they can update their templates, and move cards in dire need of reprinting(VS Seeker, Enhanced Hammers, etc., along with now-rotated cards that gave certain types a lift in their day: Blacksmith, Korrina, etc.) to NA's SM3, as by the time their Japanese versions come out, the first run cards in SM2(to be released in the Americas in May) will already be out of the printers, meaning the Best of XY, if it's released in America, won't make it to SM2, meaning it will be likely an SM3/Promo product(projected to be released in the Americas in August)...
But please, oh please, don't reprint Night March, though Battle Compressor is ok(as that could speed up the slow GX-era meta so that the no-first-turn attack rule has a legitimate reason to stay as-is: In my opinion, slow metas could cause temptations for the higher-ups to allow 1st-turn attacks, as after all, if the game is too slow to cause easy T1 KOs before the opposing player has a chance to act, then it's easy to think "Why not?", when in reality, 1st-turn attacks could make the game like solitaire if the 1st-turn attacker has enough to KO a lone active to end it before the opposing player has a chance to move)...
