If anything, since there's going to be an extreme increase in players, server numbers will go up, too.. sounds like a good thing, but when there's so many servers up it's still going to be difficult populating them.
Already with only a few hundred people online, it's still difficult to find out which server is favorable. And having to go through a couple hundred servers sounds like a headache to me.
But as problems arise, we always find a solution for it..
TL;DR: I'm anxious for it to happen.
