X-Plane 11.00 is out! Release candidate 1 is it. It's out the door!
If you've been waiting for Steam - you can now get X-Plane 11 on Steam.
If you already own X-Plane 11 from our website and you had installed the release candidate 1 patch a day or two ago, there's nothing new to download - you have the latest version of X-Plane, and it won't auto-prompt you until we have a patch.
If you're waiting on DVDs, the materials have been sent off to the duplicator, so my totally-uninformed-guess is maybe a week or two.
