I haven't heard much in the way of definitive information, honestly.

What I'm hoping is that people who are currently subbed and continue to be subbed through the 2.0 transition will all be invited into the 2.0 beta and that they can continue testing & playing throughout that period of time. Everything that they do in the game at this point continues as regularly, is saved, even through the 're-launch'.

I don't know if that's what their planning, but it's definitely what I'm hoping! Haha.
