CX is moving towards a 5-tier system like many airlines have done. Green, Silver, Gold, Diamond, Diamond Plus.
With that benefits will be "enhanced" appropriately. Green - just earn points. Silver - Green + priority bag tag and check-in. Gold - J lounge + Silver. Diamond - no more F lounge. Diamond Plus - F lounge. SP will be adjusted to each earned status, but SP will accumulate much easier if you fly in premium cabins and/or pay in premium fare classes. With the new system, one can even make Diamond Plus if you fly between HKG and TPE in full J fare twice a month.
Anyway, that's all I can say. Enjoy CXboys.
