Rocket Giotto and Mozzafiato FAST

I saw a youtube video about the new Rocket Giotto and Mozzafiato FAST versions. They look like an upgrade to the "R" but with a shorter heat up time and new case design/colors. The Rocket Instagram feed shows a pallet of these being shipped. Does anyone know when these might be available in the US for preorder? Details are limited and I want one!
