Revamped Argent Tourney mounts, EQ Manager coming
The blues have just announced today that "in an upcoming minor patch" (probably patch 3.1.2 or so), the faction mounts that you can get from the Argent Tournament will "have their visual appearances improved," apparently to better match in color their factions. Mounts already purchased will be automatically replaced; if you want to get the original mounts, you'll be able to buy them for 5 Champion's Seals and 500 gold (discounted by faction).
In other "upcoming minor patch" news, the in-game Equipment Manager is coming, as they have been promising. If you're not sure what I'm talking about, it's basically Blizzard's answer to Outfitter et al., and was originally meant to be included in patch 3.1. Some bugs kept it from coming out on time, but apparently we can expect to to soon (or rather, "Soon™") be able to switch gear sets without mods.
