They finally put the new Guild UI into Beta. Here are some pictures:
You are able to see the guild perks, upcoming events from the in-game calendar, and you can now see the professions of everyone in the guild. It’s pretty nice! I didn’t show a shot of the actual guild roster page, since it would’ve been mostly blacked out due to not wanting to actually show everyone’s names. However, this should give you a feel for how neat the guild UI is going to be in Cataclysm!
