The problem with approximate release dates is that people expect you to meet them
People have been getting annoyed that the March estimate wasn't met, if I were TGC I would personally not say anything until I had a rather "exact" approximate to share. Maybe that's why they've been fairly quiet on the release date front?
A full list of the commands already added / working in the new build would be nice to share, as would any ready help files / syntax. That way people would have an idea whether what they want from AppGameKit will be more or less possible.
