Guess that depends on the aircraft...
Airbus FBW family: aircraft will maintain bank angle and zero vertical acceleration (your 1G analogy).
Conventional aircraft: the control wheel is spring-loaded to neutral and thus will return to the center as the A/P drops off. The aircraft will slowly return to 0 bank angle due to the positive dihedral of the wings. As to pitch, the aircraft should start to climb as it rolls back to 0° bank angle...
