Keep in mind we don't know the final cost of the software itself; the $2,000 that Yoshi quoted was for the 6 Optitrack cameras, USB 2 hubs, tripods, markers, and halogen spotlights he bought. It may be another 2k, or it could be considerably cheaper. But yah, a nine month lead time is going to be a bit much. But I can think of one reason for it. A good sized manual. Those do take time to write, particularly if you have to pick the brain of a coder for the fiddly details that are 2nd nature to them, but no one else. And if Yoshi is writing it himself, then a good technical editing and clean-up can take just as long. The one thing I wish I knew for certain is that Yoshi's app =is= coming out. That way I could start saving up for the cameras one by one........
