I agree with the sentiments of most here. I will however say that I can understand why people who have donated money towards the project might get a little impatient if there are further delays.
Personally, I'm sure that Ady will finish the project. To be honest, I'm looking forward to ESB:R more than Star Wars VII. Taking on the rest of the saga will be a mammoth task, but there is such a huge following and excitement towards the project now (over 70,000 fb likes!) which gets me even more excited about the future of Revisited.
