Actually, I'm not. Major guilds from many games (WAR, AION, WoW, AoC, etc) already had branches established for this game shortly after its early announcement. That's what hardcore clans do. This isn't just for SWTOR either. There's already clans getting prepped for TERA and GW2 as well after their early reveals.
Just because you may not be a part of one (or maybe you do) does not mean other people are the same way.
