I'd bet field grade will be under a grand and service grade will be around a grand. It will be tough for them to sell 10,000 a year when you have to jump though all the CMP hoops and have no idea what you're receiving if they start at over $1,000.
The pricing at the beginning might be a little difficult because of the pent up demand but 10,000 a year for 10 years straight is quite a few guns.
