I have a couple limited edition as well as first run stamped Zeus. It is my recollection that the limited edition were the special run of Z plastic that look like ESP. They were sold at last year's worlds. Does anyone know for sure?

My first run Zeus looks to be ESP, but it doesn't specify the type of plastic on the disc.
