Aon ene will be the most popular sharder (per upvotes) by about 10,000.
I think the only RP that will survive is SE, most people will go slightly inactive. (They will come on once in a while but their children follow in their footsteps)
The shard will still be an awesome place full of amazing people and nothing will ever change that.
Edit: And I'm still going to be a single pringle.
