I would still bet that its life will get extended. Every time that the AF has actually moved to get rid of them the Army jumps up and says, "yes! we'll take them off your hands," and suddenly the AF grudgingly extends the service life because they don't want the Army to get back into the business of having fixed wing aircraft...
I heard USAF at point offered to sell the A-10 to South Korea. Pretty clever of USAF if true. They were not 'retiring' them but still getting rid of them AND not giving Army a chance to say 'we will take over the A-10'.
Lucky for US Army, South Korean govt supposedly declined the offer.
