With the global economy the way it is now I'm a bit more conscientious with how I spend. $30.00 is not expensive; I guess the only thing that irks me is the delay but as an aspiring software engineer that's understandable.
How about a suggestion. As opposed to a big roll out of features how about a micro-transaction scheme that allows the end-user to be satisfied in the interim and ED to have revenue coming in the interim?
For example the new Su-25 3-D model would be available to users of FC2.0 for "X" amount of dollars. I'm just throwing this out there; might be a bit too late for this sort of idea as I do not know the intricacies of code that ED is using.
