Profile Pics are sort of on the low priority list. Fixing the more important and less cosmetic features are taking precident, and since we don't know when those will be fixed, there is no ETA on profile pics. If there is a breakthrough, could be today! Or, it could be fixed 10 years from now (I hope not)
As low a priority as its percieved... Its so much easier to follow posts via profile pics...
As for the timeframe.. sounds like BFL are managing the forum
