Nemesis emailed me today saying:

I just pre-ordered 10,000 days, the guy in the store was on the phone while I waited and he says ‘hey, how many Tool are you getting…. yeah, whats the go there!?’. I said, thats actually why i’m here, is it worthwhile pre-ordering Tool, and he said that they’re only getting 10 copies. Apparently Australia ordered 50,000 but are only getting 20,000 copies for some reason.
There will eventually be more, but if you want it Friday afternoon (thats when he said to pick up my copy), it might pay for fans to pre-order!
JB Hi-Fi also seem to confirm this on their website.  If you want the CD straight away, it may pay to pre-order ASAP.
