@594362: Most likely right. But we have a while to go yet. Off the top of my head we lack EX's for the following: Palkia, Dialga, Mesprit, Uxie, Azelf, Suicune, Jirachi, Arceus (maybe up to ten of them if they decide to do one for each type in the ccg), Virizion (possibly depending on what happens with Plasma Gale), Shaymin, Manaphy (Maybe), Victini,Heatran (maybe), Thundurus (both forms), Latias, Latios, Giratina Origin, Landorus original form, Tornadus (alternate form), Regirock, Regice, Deoxy (four forms).
This list ignore some other aspects, such as many of the dragons having another type in addtion to their own, or that some Pokemon have two types, like Victini, Jirachi and Heatran.
Personally I dislike the idea the Articuno, Zapdos, Moltres, and Lugia are going to make their appearance here as Plasma Pokemon. It seems wrong somehow, especially since they weren't even used by Team Plasma. But whateva.
