Yes, I'd probably wait on the new one. I own the old version and since I'm mostly a full frame shooter now, it is adequate, but it does have some weaknesses optically, flares quite a bit, and then of course there is the SDM (slow and prone to failure). Even if you could get an old version for half price of a new one, it's probably worth it in the long run to go with version II.
