That's absolutely more than reasonable. I know you guys work hard and spend way more time than we deserve on these modules. Impatient people will be impatient.
However, (and this isn't directed specifically at you guys(just a general statement about announcements)) it seems ED has the best course of action when it comes to announcements. Take the F/A-18C for example. It's been confirmed, and it's a long ways off, but their announcement was essentially "Yes, we're doing the F/A-18C. It will be finished when it's finished." and that was that. Too much hype for an announcement/release can do more harm than good sometimes. Sometimes it's nice to get a tease, but after a while it causes people to become impatient if there's a lot of teasing being done, especially for something like a new project. ;)
