All over eBay, I see boxes of 07-08 UD Black being advertised as containing the following sets:

* Triple Player Jersey (# to 50)
* Triple Player Jersey Gold Patch // (# to 15)
* Triple Player Jersey White Patch // (# to 1)
* Quad Player Jersey (# to 25)
* Quad Player Jersey Gold Patch // (# to 10)
* Quad Player Jersey White Patch // (# to 1)
* Six Player Jersey (# to 15)
* Six Player Jersey Gold Patch // (# to 5)
* Six Player Jersey White Patch // (# to 1)
* Octo Player Jersey (# to 10)
* Octo Player Jersey Gold Patch // (# to 5)
* Octo Player Jersey White Patch // (# to 1)

They're also to be found on this sheet, which is supposedly a complete checklist of UD Black:

And Beckett also has listings for them. However, they are not mentioned anywhere on Upper Deck's web site, neither on the Black press release...

...Nor on the Black checklist page...

I've been searching the Bay for these things ever since Black came out, and I have yet to encounter a single one, even though I've seen plenty of other 1/1s from the product. It's important to me to find out because these sets supposedly contain cards of a guy I collect, and I need to know whether they really exist or whether Upper Deck yanked them at the last minute. Anyone have any information?
