Hey guys, this is a little late, but apparently people who participated in the beta will get booster codes for when it's actually released. Here's the official post:
As a thank you for their hard work, closed beta participants will receive booster packs based on the number of hours they played, but we’d like to give you a chance to earn even more boosters by giving you the breakdown. August is the month to up your playtime in the Pokémon TCG Online and earn more boosters for getting in on the action. Here’s how it works:
1 hour or less of game play=1 booster pack
1+ hour to 5 hours of game play= 5 booster packs
5+ hours to 10 hours of game play= 10 booster packs
10+ hours or more of game play= 20 booster packs
When will you get those booster packs for participating in the closed beta? After we conclude closed beta, all accounts will be erased, and everyone will be reissued booster pack credits equal to the number of codes they entered. The 20 free booster packs players received at the beginning of closed beta will not be reissued. Each player who participated in the closed beta will get booster pack credits based on the number of hours he or she played the game. The more you play, the more boosters you earn. It’s that easy!
So rev up that play time and start earning more booster packs. The end of closed beta is fast approaching!
So let's get some more matches going so that everyone can get a bunch of packs for the actual game.
