Zagenda has one holding left but noone knows when or if Sun is going to siege it from them any time soon. In the meantime, the amount of hatred towards Sun seems to be increasing. Why? Well, last night they did pull a very nice tactic in the Sea Tower but the problem is not the tactic itself but the fact that with their numbers is really hard to win them. Currently, Sun has good players with really good gear plus more people than any other clan. Even more so, if any clan plans to siege a Sun holding they better have a lot of gold to hire mercs because it won't probably work any other way.
Sun members are probably enjoying this whole situation because they are winning their combats (winning is always fun even if you do close to nothing) and all this rage towards them is probably making them a closer bunch. The rest of the server is also enjoying theirselves because this game is so great but it's also a MMORPG and a lot of people doesn't like the presence of such a force that noone can take by himself.
So, what can we expect from the future? Well, Sun might downsize a bit to decrease the hate that is currently building up or enough people will decide that's it, create an even bigger alliance to take them down. If neither of this happen, well, Sun will remain the USA clan in Agon for a long time.
