Ludei is in charge of all of this, releases, announcements, etc. From what I've seen they do not communicate that often with Scirra. We need to keep on them in the forums, twitter, email, etc and just wait for it.
They were supposed to open source the plugin and basically leave it up to us, but as we know, Ludei doesn't share roadmaps with the public.

Let's remember, they are a start up, with a small team, and they are giving us a free product. They only have one goal and that is to get another round of funding to keep going, so they are really targeting the product to investors or potential buyers, not us. I feel once the product is more stable or they get bought out, they will become more consumer focused.
