USAF F-35A levels to be reduced?

In view of the following, how many F-35A’s will the USAF order?

The USAF Chief of Staff is talking of proposed cuts to the USAF fighter complement:

“The changes, if approved, would reduce the size of the USAF fighter fleet to 54 squadrons. Depending on the number of aircraft in each squadron, the total number of fighters would dwindle to between about 1,080 and 1,300. That number is significantly below the USAF’s plan to buy 1,763 Lockheed F-35As, which would serve as a replacement for all its A-10s, F-15s and F-16s.”

Would a cut of ~450-700 F-35A’s have a significant effect on F-35A’s flyaway cost? Additionally, would export customers with a need to acquire F-35A’s be able to get them earlier than currently expected (but at a higher price than they would otherwise have to pay)? This could be good news for non-USAF customers who might be able to retire F-16’s rather than pay heavy maintenance costs while waiting for their much delayed F-35A’s.
