Do not skip stuffs.
"... back in time to 2003 on .." is reference to experiencing the old updates first hand again. It doesn't mean we will have the game as is, as it was on the very first launch.
Right now we have the game as it is on every other server minus a few exp and monster location tweaks. The site also clearly states episodic updating, meaning we should be starting in 2003 or as close to it as possible and going from there. The way the server is at this point is starting at episode 16.x and working backwards till they figure out where we're supposed to be.
TLDR: What they said the server was going to be and what it currently is are two different things.
