The xStream price is insane, and like Steven, I was thinking of getting it for C4D, they say there will be a special introductory price, let's hope it will be reasonable...
Now about Complete, I agree with Chipp, these feautures need to be in this version, as for animtion, they don't say anything, guess we'll have to wait. But if Complete has all the Infinite features, minus production and pipeline integration features ( or so they say in the newsletter), like maybe g buffer and camera tracking, then I think Complete will be a great version.
