I've been watching the work on A8 on a daily basis, and I want to laud all the contributors for their dedicated work.
(I'm not a python programmer or a proficient artist, so I remain just a spectator.)
I try out the A8 svn from time to time and see that the function of many controls has not yet been re-implemented.
I have the impression that this is due to the lack of artists to create the targets.
Based on an a purely empirical observation of the rate of progress, I would think that A8 will take at least another year.
I know that it will be done when it's done, but is there any ballpark ETA?
