Think there will ever be a reroll of blue?

This subject has been discussed before and I think that this is what will happen. This is all SPECULATION.

Once the developers have released Velious, they will focus on the long list of bugs, prioritized. Work will be focused on getting all of the content and game mechanics in line with what live was (or as close to it as possible). Once satisfied that they have hit their target, a new server will be stood up (leaving the current server in place). The new server will progress at the rate that live did. Items removed or changed will be be done so at the correct rate of change. It will be a true classic experience. There will be no slow progress of classic changes or broken content / game mechanics.
I think they may then opt to add some additional content to the "old" server in order to get people to play there as well. Perhaps they will add some additional raid content? Perhaps it will be left alone.
