Your MMORPG cherry?

I've been following the recent publicized info that EverQuest 1 will be releasing a server that is much reminiscent of what many old EverQuest 1 players called a 'Classic' server; Sony call it a Progression server and it works like this:

The server/game world is essentially the same as any other server, except-->
Expansions are simply disabled for everyone, until certain criteria in the current one are met.

This means that global changes like the UI, maps and similar will remain in the game while expansion-specific ones like (gasp!) the Vah Shiir, Iksars and the two new classes Berserker and Beastlord will NOT be in the game from the get-go.

They've hinted at the fact that in order to release Kunark, you must slay Lady Vox and Lord Nagafen. I wonder how long that will take ;)

A recent article was posted on mmorpg.com that explains things in basic terms, and that can be found here

It's interesting, the amount of support the Progression server is getting and even the nostalgia that I myself feel when thinking about the possibility. I do think people are expecting a nostalgia beyond what most will realistically feel, though. I'd quote EQ1 developer Maddoc (the person who seems to be 'in charge' of the server) on this, but I can't seem to locate that particular post of his and I'm too lazy to read through 40-60 posts to find it. So I'll paraphrase:

Your first MMORPG is like your first kiss; Its a magic that can't be duplicated. The progression server allows people to play through content how it was meant to, however.

Only time will tell how the Progression server will live up to expectations.

How long will it take before the entire game is unlocked?

Will the amount of players the server will get amount up to the visibly present (I'd say large but I can't justify saying that) support its getting on forums across different sites?

Will the nostalgia still be there?
