Right now the cards are in the air as far as time tables for a 2nd
Closed Beta or a Open Beta due to SmileGate's development time.
The upcoming updates for potions, pk penalties and anything else
will be tested in-house first by Aeria but pending their approval will
be added to the official server for whenever that gets opened up again.
While the decision is of course up to Aeria, I'm personally for opening
up a 2nd closed beta as soon as the potions and penalties get tested.
Keep it running until the islands/turfs can be incorporated and tested
and start Open Beta once the islands have passed the test.
Additionally, you will not have to download a new client, as
everything can be updated without downloading an entirely new client.
