I would venture to say that since they read the forums, if they had any desire to discuss everything they are doing/planning, they would. The way I see it, there are two problems with them popping in and dropping hints.
#1: If I was the author, and had a lot of REALLY cool stuff I was gonna do, and I told everyone...... and then ran out of free time, and couldn't get it all done... I think you'd be pretty pissed. In fact, you might start bad-mouthing the emulator just cause I wasn't able to make life perfect, just better.
#2: Whatever free time I had, I would spend trying to make the emulator better, rather than try to explain, in detail, to everyone who wants to know (and there are a lot of people who do) what and how and where.
Make sense?
