I have just checked to see if Flights that run on the A300 at the moment are on the A300 for summer 2013 and the bad news is that the are A321's next summer. Flights I checked Were:
Friday:
ZB564 MAN-TFS
ZB569 TFS-MAN
Saturday:
ZB654 MAN-AGP
Sunday:
ZB655 AGP-MAN
This is my indications that All 3 A300;s could be going this year
