What are the odds that Nintendo will...

...do another promotion similar to the Pokemon X/Y one?

Specifically, where you register the serial of any qualifying system and the PIN of any qualifying game?

Hoping they do something for Super Smash Bros and/or Pokemon Sapphire/Ruby remakes.

Likely they're do it again for SOME game, but there's no way to tell what the chances are of them doing it again for the next Pokemon games, or Smash Bros or anything. I don't think there was any tell that they were gonna give away a free download game with Mario Kart 8 or that Pokemon thing until they said it themselves.

I can see it happening for Super Smash Bros. Wii U actually not so much the 3DS. I would LOVE another Fire Emblem/Shin Megami Tensei promotion best one imo since I had both games and basically got an extra $30 to spend.
