Oman Air will be getting 2 A 332s and 1 A 310-300. The 2 A 332s are currently in Australia being chartered by the Aussie Govt to transport their troops here and there. The aircraft are in charter configuration and will be reconfigured to WY's wishes.
WY will be using the A 332 to LHR and A 310-300 to BKK and some Indian routes.
However for them to get 2 A 332s that means its most likely its going to be a daily same plane service from LHR to BKK via MCT with the 2 A 332s.
WY will also be launching KHI, LHE & ISB nonstop from MCT with the B 738 from this November. This means that GF's flights from MCT to Pakistan will soon come to an end as will its daily unprofitable MCT-LHR service.
