Well, after much hype, presumtions and server crashes, it looks as though the Lateralus Vinyl is available, both on Toolband and Toolarmy. From what I can see they’re not Autographed, holographically or otherwise, and the cost is US$44.99 + US$16 for postage to Australia. That’s about $81 Australian!
I hope the autographed copy is not much more expensive than that!
