While the announcement doesn't go into details about the rationale, it notes that there were late-surfacing issues uncovered by players on the test realm that required additional maintenance to correct, forcing the team to bring the patch back and polish it a few more times. A definite time will be posted to the community as soon as it's available. It's disappointing, certainly, but the idea of putting out the game's first major patch before the game had even been out of retail release for a month may have been overly ambitious.
