I seem to recall similar comments like this before Legion was announced at Gamescon. Again we have more than enough information here to make an educated guess as to the earliest date for release of the next expansion while not having much more than 6-10 months between it and Legion's last patch. Blizzard has got to get moving on this or risk another 12+ month content drought. Again the lead time on expansions is huge and people need to take this into account when discussing announcement/release of new expansions.
