I would think it likely Star related stuff will indeed disappear by Mar 30th. Apparently one of the Star-liveried planes, N700UW, is about to emerge from painting into the new AA livery from ROW shortly if http://www.airliners.net/aviation-fo....main/5981615/ is to be believed (pics available there too). To do that, it'll probably ferry to CLT overnight, in which case it's likely to be trackable at http://flightaware.com/live/flight/N700UW

The logos on the aircraft wearing regular livery are I believe just "stickers" that can be easily replaced, likely by maintenance, and will likely be in quick order.
