My motto, when in doubt, wait. However, your host has already shafted you, so to speak.
What I suggest you do is install 2.0.9 beta into a subdirectory and give it a try. You could also copy your current installation into a new directory, change the mainfile.php, back up your DB and give the upgrade a shot to see what will happen. This way you will have your original files and DB and go what ever route you want once the full release is out and tested.
If anything, it's something to do in the meantime
