IGA has updated the official site with details on a Dec. 6th release for the Entreat Plus vinyl at the Universal store.
Note: "This a strictly limited and numbered edition that is only available from the Universal Cure store. Each disc is manufactured with its own unique pattern: no two discs are identical. The marble effect pattern on the vinyl is not printed but is created as part of a manufacturing process which means every disc will display a unique marbling effect, with the colours chosen to be sympathetic to the front cover artwork."
This appears to be unavailable to North American fans, most likely due to Elektra/Rhino having the rights in this region (Elektra/Rhino is releasing it here, not Universal), though that's only a guess at this time.
