knowing how it is with additions of expansions, the newer models of zones will replace the ones we said we have that are old. Newer editions are always a "we do not know" till they are used and we go "oh no! we just made eqemu into bugzilla!" hehe. Not saying it will, usually something important does break when you upgrade to new expansions. fun huh?
Edit: What I said might be wrong so if a dev or admin could confirm or deny the possibility, it would be nice. ^.^
