Sander indicated (well) below that he hoped to have it ready in July, so I checked in periodically. Just looked today, a few hours ago. It's up on the site! I have placed my (waterline) order, but a full hull option is available, as he'd hoped to be able to do.

Here's the item on the site:

Be sure to check the 1/700 full hull box. (It is not the default...)

Enjoy! I looked forward to mine!
