From what I can tell, the Holiday Collection is largely the Dinosaur and glovetan leather accessories that you see online now.
The hologram items should be out for Black Friday, like last year, and I imagine they'll have a smaller inventory in order to sell through before the Semi Annual Sale. We should see the second half of Pre Spring go online then, too, with the sequin car items and the rest of the RTW, but that'll all be excluded from PCE and Semi Annual Sale.
