Pokemon-TCG.com has now confirmed the new modified format:

Expedition
Aquapolis
Skyridge
EX Ruby and Sapphire
EX Sandstorm
EX Dragons (When it is released, I guess)
Promos (starting with Kyogre 001)

Well, many people thought that the new format would be EX R/S on, and others though it would be Expedition on. I, for one, though it would be EX R/S on because Nintendo would not want to be involved with Wizards' sets. Guess I was wrong. Anyways, this will leave some of the good trainers in such as Oak's Research and Copycat, so we can all be happy about that.

And RK, I remember reading in some post a few days ago you congratulating me for my site being back up. Thanks for that! Since it's my b-day, I will be getting some booster boxes and can get more scans up. *rushes off to parents' secret present hiding place*
