The product page is saying December now... so I'm not sure if they released it already and will have a second batch coming in December... or if they have pushed back the release to December.

The news though is that they have listed the Trailer now as well, for December at the same price - au$1400.

If the robot part is now being released in December, I don't know why they would need to do that, unless the shipment from Japan or America was held back to include the trailer part.
It just seems like too much money to have hit at once... and really needs to be spread out a lot more (like in other countries, who now have a year between the two expensive parts).
