I'm sure you're busy and this patch certainly took me by surprise (3.5 months since the previous major patch and relatively smooth so far, Ulduar/3.1 was 5 months and Wintergrasp caused problems for everyone).

Just thought I should mention that details of the new raid instance Crusader's Coliseum/Trial of the Champion will start trickling out (Blizz is apparently aiming for 1 boss per week), Blizzard coverage here, some coverage at MMO-Champion here, and data from WoWHead (including PTR stuff that may not actually end up being available on live) and GuildOx.

I noticed the servers were down unusually long yesterday (patch-day long), but didn't know that this was in the works.

Thanks for the heads up.
