>>55559003I'm thinking SIR Bianca is gonna be the big chase card this set. If I'm remembering right, Raging Bolt, Iron Crown, and Iron Leaves are probably gonna be among the highest priced pokemon for their competitive viability, but I don't think they've got enough appeal to drive a particularly high price with collectors. Really not sure about Ace Specs. It depends on how difficult they are to pull. They're gonna be desired, but I doubt the they'd make such staple cards TOO hard to pull. I'm predicting pullrates somewhere between radiants and IRs, with most of them settling around 10-20 bucks, but that's just a wild guess. Prime Catcher in particular is gonna be the big one.
Prices at prereleases are gonna be a crapshoot. No one really knows so you're just going back to old pre-internet playground rules. You might find someone willing to pay the heavily inflated pre-release price listed on the internet, but most people would rather wait to see how the price the settles, especially since they still have two weeks after official release before these cards are legal.
