So it has been confirmed! ThriftyGuy ran across this and ThriftyGrl reader Lisa was kind enough to confirm it in a comment... It seems that Money Savin' Momma (from EngineerADebtFreeLife.com) straight up asked M80 (you go girl!) about the Old Navy Weekly reset and they officially confirmed that the coupons from Gobblepalooza are taking the place of ONW resets from now until the first week of December. (Which hopefully should mean a reset in the second week of December!)

Thanks again to Money Savin' Momma for pursuing the issue and getting us all a straight up answer! : )
