Another positive about the delay is that Ady will probably have seen Episode 7 by the time he comes to finish ROTJ:R so while it might not be a major priority for him it would let him know if his edit ideas will create major inconsistencies between his OT edits and the ST.
I believe it was in this thread that Adywan said 7+ won't affect these releases plot-wise - but I could be mis-remembering.
