I won't be watching this. I've been consistently disappointed with every Live Letter for the last few years.

New story and raids and such are nice so it's not like I don't look forward to new patches, but those are a given. We don't need a Live letter to tell us those are on the way. What interests me in Live letters is class changes, new systems, developer insight going forward and things added that I didn't expect, to feel excited for. Usually live letters boil down to "we can't change this, the servers will blow up if we change that, we plan to stick to the same safe formula for another 10 years please look forward to it, we'll think about it, maybe in 7.0 and here's something you've actually wanted ...done badly".
