Tampa - using the A330, likely to be A350 or Neo?

Hello Virgin Experts!
I have booked a flight next Easter, returning from Tampa to London Heathrow on 11th April. At the moment it says its an A330-300. Anyone have any thoughts of whether that is likely to be replaced with an A350 or A330 Neo?
Booked in Upper Class so very much hoping one of the newer planes takes over.
