Nihkon,
You bring up some excellent questions! I'll contact Mark and see what he has to say. My guess, at this point, is that the four month countdown will begin on the "end date" of the group buy. As for any additional incentives to keep Shrockworks diligent with completing our products, at this point, I would think money. Most of us are doing 50% upfront and the other 50% upon shipment. They'll have a lot of resources invested in this Group Buy and if they're sitting on 20 products and lets say the average product costs $1,200, well $600 x 20 = $12,000. However, that's just me drawing my own conclusions.
