I don't know how long it takes, but within the last couple of weeks at my CCO they have had Barbie, Strange Hybrid, C-Shock, Novel Twist, Rushmetal & Flashtronic, Slimshines, Moonbathe & Balloonacy. So anywhere from February to August, I don't know how they do it though because they got Barbie stuff at the same time as Novel Twist, and they came out at least 6 months apart.
