There are many more considerations for involvement of guilds and even PvP on the table however, nothing can be said of this yet. I'd love to give you all more specifics, but at the same time, what I have learned beyond the E3 demo is under NDA (via the VIP party they threw) and because they have assured me that the best is yet to come for E3. I respect their dedication to releasing very real and concrete information to their fans and listening to their fanbase as they develop something they hope to be proud of.
