I just went to a prerelease at Retro, Perth, Western Australia and in the 6 you start with the were draws ranging from no Exs to 3 Exs. I somehow drew both Cobalion FA and Victini FA. The tournament manager even drew a misprinted card where the complete front of the card is missing except for the yellow border, Compared to the Exs being drawn, there was very few secret rares drawn. I only heard of shiny Blastoise being pulled by 1 of the 50 people who attended. After this prerelease I think that Plasma Storm's secret rares and Ex pulls will probably be all over the place. The pulls might even be more crazy than Dragon Exalted's pulls. I could be wrong though and this might just be a prerelease thing but we won't see until the booster boxes are released.
