There's always going to be something better. Start now and get used to everything. Plus, it gives you plenty of time to mess up and default back to the install until 2.0 rolls around. Your members, OTOH, may be a bit peeved.
I cant see 2.0 being released in the next six months, not if they are going to step back and start again. Though the programmers are top notch, you really can't discount a few false starts, plus their will have to a dev release phase to allow add-on developers time to adapt their wares. I just think the end of the year is the earliest that a stable 2 will be going.
