A collector's edition has been announced along with a release date of September 16 2014. The set includes 2 CDs (25 tracks total), a soft 3DS carry case, and 5 CollectaCards from the game. Price point is 69.99$ and they are only releasing 5,000 copies of the collectors edition. I'm thinking about it but the price seems a little steep to me.

All preorder copies get the smaller 5-track disc. Basically you're paying $30 extra for a 20-track CD, a 3DS case, and 5 cards that aren't worth anything. Way not worth it IMO.

@starvinggamer: Yea I'm inclined to agree with that assessment. It might be worth it if it had the entire soundtrack on disc. I feel like the 5,000 copy thing is just to build hype.
