Well, it is now the 20th of December and I have no shipping notification for a Press. However, Sam did list a 9-day window for the first shipments (Dec 19 - 28) in their latest blog post. My order number is definitely in the very first part of that range of orders, but I'm not worried about a pre-Christmas delivery.
As for the Cube 3d gen, they have released a new firmware update and things are looking pretty good, not only for single color but also dual color builds. I suspect they have a big backup of cartridge orders and thus it will take some time to fufill those. However, check out cubifyfans.blogspot.com and you can see Tom Meek's progress.
