Question about seat requests

I've recently booked flights in PE on the A330 from MAN to MCO, for next February.
I understand that I can't currently make a seat request because the system is being worked on. I've also read about the separate issue of PE seat requests not being available because of the refitting of LGW/MAN/GLA aircraft.
However, it's only the 747s which are being refitted, not the A330s - although the VS website doesn't mention that. So when the seat assignment facility becomes available again, will I be able to make a seat request for my A330 flight?
Does anyone know please?
