I'm expecting pearls across the board, POW is the only pearl left in the line. Idol is stronger than anything they've had in the HP4 line anyway, so HP4 missing a solid isn't a big hole, they have their hybrids covered with the Fused, Danger, and HYB, solids are Idol, Show Off, and Ink, so HP2, 3 and 4 lines get pearls I think, and with the Exist and AOSO getting discontinued so recently, I think they fill those holes at the end of the year.
Crush It seems to be the HP4 release like has been said, pearl Idol is a no brainer, and we haven't had a pearl Show Off yet, so I'm expecting that too. No inside information, but knowing Schlemer, this sounds like what he'd do.
