According to Ruliweb, Pangya Portable will be available in three packages - basic, limited and limited special.

Basic Edition

Contains the game and a premium members card. This card allows players to have the following privileges:

• Use a total of 9 costumes from the PSP game in the online PC version.
• Newcomer's pack when joining online which includes 30,000 Pang Points.
• Join in any future Pangya related events.

Limited Edition

This contains the game with an alternative cover.

A 16.5cm of Kooh.

PSP pouch.

OST

And of course, a collector's box to keep it all in.

Limited Special Edition

Has everything the Limited Edition has but includes a Pangya themed PSP-3005 Piano Black. No photo of what it will look like yet.

I don't think there's a release date for the game itself either but, it appears pre-orders are being taken on December 10th in Korea.
