I think it’s 100% guaranteed Epic Games will add Nvidia’s WaveWorks support to Unreal Engine 4. I mean Epic Games is partnered with Nvidia and has Nvidia’s PhysX physics engine supported in Unreal Engine 4 just like in Unreal Engine 3. I hope FLEX support will get added as well as FlameWorks, HairWorks, etc. Everything from Nvidia to get supported in Unreal Engine 4 from Epic Games will be amazing.
