The last update given about stuff in the 1.19 patch was posted as 2am Japanese time by the dev. If he's still in the office at 2am to post that, that means they're probably working their asses off and doing major over-time to get this patch out, with all it's content, on time. Even if it is delayed by a few days or weeks, it'll be for all the right reasons, and their dedication to fixing this game up is pretty admirable, compared to a lot of other mmo developers.
(Yes Mythic Entertainment, we mean you and your extremely still-broken Warhammer Online with it's million-and-one bugs that have never been fixed since beta)
