An official Aegis server has updates, so I'm right, although you are also right.
The eAthena servers can update more and have more features, but they often take things too far. I think Talis prefers Aegis because it's closer to the official game, even though there's no other logical reason (aside from the difficulty and expense of switching) not to switch.
Anyways, that's why we don't get updates often. Enjoy what you have already - I doubt you've visited every dungeon and tried every class available in this episode, so why worry about the new stuff in the next one?
