I am not aware of any major changes in the pipeline. However, given that when they introduced the flat beds in Club World, it was heavily promoted as "New Club World" and often abreviated to NCW, I think they will have to come up with a new name for any major upgrade to the product.
They have been continuing to upgrade their Old Culb World (Cradle Seats) product that remained on some 777 and 767 aircraft. This process has often been referred to as "Dusking". I believe all the 777 have been completed (the LGW-based GE-powered ones were the last to be done), but there may be some long-haul 767's still to be completed. The short-haul 767's remain in standard Club Europe config. The "dusked" 767's are now in 3-class config - Club World, World Traveller Plus and World Traveller.
