Estimated release dates for the DeEd’s are an inside joke here. One estimate provided from Harmy himself was over a year off. So, in short, you’re not going to get accurate estimates, except maybe a few hours before the actual release you might have a shot.
Now, if you’re not satisfied with that, I can provide you with some wildly inaccurate estimates based on my patented Predicto-Vision method. ROTJ DeEd 2.0 will be released 3/14/2016 at about 3pm UTC, ESB DeEd 2.5 will be released 11/26/2016 at about 10am UTC, and ROTJ DeEd 2.5 will be released 6/2/2017, completely coincidentally also at about 10am UTC.
