Bluedog, you can buy it now from Bohemia Interactive Australia. The core costs a mere $140 US, and "nicely equipped" (OPFOR, various maps, USMC, US SF, ADF, and so on) it runs over $500 US. Still, people and not just militaries are buying it.
I wouldn't purchase it, of course, nor would I recommend to any other OFP fan that they purchase it. That's a big-ass chunk of change.
Oh yeah, and it's only for sale to private individuals outside of North America (Coalescent Technologies Corp. has the NA license).
In spite of the fact that they haven't been posting screenshots, I do have it on good authority that OFP2 is in active development.
Oh yeah, and Kangaroos:
