I don't mind the hand levels from 9-12, but once you've had them for a while they do get boring. When I first got to level 12 it was great- now it has been there so long I hate it. Hopefully I should just squeeze into level 13 before they all get updated- it depends how long it is being delayed. My guess would be that it will be happening mid to late December, although obviously I have no idea.
As for what rank I will move to, I'm guessing about level 18. I'd like to point out that there is no guarentee that level 18 will be the same as it currently is though. My guess would be that the 30 new levels will be interspersed between the current 30, so that what is now level 18 could be somewhere in the mid 20s after the update etc. I would certainly expect the current level 30 icon to be up in the late 50s. They may even remove levels completely- a lot of 1-9 could be removed/changed to make them more interesting.
Ok, speculation over- can't wait to wake up one morning and see that everything has changed :)
