I'd be astonished if they re-enter service. The A330 fleet is grounded with only B789/A350 flying out of LHR on mainly cargo flights. If and when the A330s return, it makes no sense to have a small subfleet with a different engine type if some of the -300s are still parked, or even worse, the new A350s are still parked!
I think the active fleet will be B789, all the currently parked A350s and then selected A330-300s, with the oddball -200s the very last to return if at all.
I could be 100% wrong on this. Again
