IMO, I see CoL shinies going up significantly (esp. Ho-Oh and maybe Lugia) and maybe Legend Cards as well. The Primes have nice artwork, but they remind me of EX cards–nothing special like the Legend Artwork and nothing unusual like a different color pokemon. That said, I still see them going up a tad bit in the future because the artwork is amazing (unlike Lv.Xs and reprints which I predict will stay at their current prices). Maybe $10-$25 depending on the card max. Then again, I could be completely wrong about everything
