Well, I was hoping that in payment for all the wonderful feedback we have just given you, you would implement all these features for us
(Well, I can hope, can't I?)
The simple answer is that I don't know. I do know that we have a full (over-full) list of things to do up until after Moodle 2.9 is released.
After that, it is really up to our friends in the Learning and Teaching department to set the relative priorities of things for us. At least we now have a good list of developments we have agreed on (and a few we might want to discuss with you further to try to change your mind). I hope we get get at least some of the low-hanging fruit done for 3.0. I will let you know when I know more.
