I am watching these events which interest as well. Let's see how it all turns out over the next few weeks.
My primary concerns have been touched on already, and I don't see a need to add more about them except I'd like to see over the next few weeks/months if the original IP holder(s) take any notice and/or any actions.
My other concerns are about me and where I am today, which has already been touched on by other some. The game is now pretty old; the technologies, animations, general graphics, style of the zones, and so on. MMO"s have made a lot of progress. Would it still have the same draw were I to play again?
My old characters, hrm, hard to say. As I recall, leveling wasn't too hard, nor was the incarnate system for the end game. It might be fun to start afresh. Otoh, some of those characters were dear friends I don't remember enough about; if my old account were made available to me I might find that a good thing.
The community will be different, would I still fit in? I was part of the RP-crowd (more or less, I was loosely connected towards the end) on Virtue. Will the roleplayers who're still interested find the same place to play? One of the nice things about the servers on Classic CoX was their different personalities. It would be a loss, imo, for them to become fully homogenized just because a critical population turns out to be necessary for server survival.
Would the developers supporting it learn to start building new content, or would be have to be satisfied with the (tremendous) amount of content it had at shutdown. If the former, would someone, or anyone, care to coordinate the general lore among the various new server/development efforts?
Would it end up as a short nostalgia run, or could it have a longer life? I don't know.
