This was from the EQ blog last month after Tyen started that rumor about a new classic server in Jan.

"Ok first off it is not. Removing one single quest can kill the entire game. This is proven over and over when you work with the earliest source code over on [something not to be discussed]. Several times I would change or remove an old quest or even just move or remove the NPC from the zone and the zone would crash or not load properly. You have to go back into the code and fix the borken strings and pointers.
The Original EQ code, as far back as we have it is the penultimate spaggetti code, there are litteraly tens of thousands of lines of orphan code that has been piecemealed and changed over the decade by litteraly hundreds of people, miuch of which has no notations or refrences after the 7th or 8th coder has changed that section over the years.
The original code does not exist, even working with the original floppys I got in August of 1998, we still have been unable to put together a working build for Everquest MArch 16th, 1999. What you see coming out of servers like [something else not to be discussed] and others is the result of hundreds of manhours of hand inputing much of the old game back into the code, a very long and expensive process, that stuff just doesnt exist anymore."
It sounds like the code exists, but it would be too much of a hassle for them to go through it and untangle it with no guarantee of it actually being classic. In short, too much effort for their bottom line since EQ is now FTP anyways.
