Will MPEG4 AVC become the dominant Blu-ray video codec?

I’m just wondering because the only Blu-ray 3D codec is MPEG4 MVC, which is an extension of MPEG4 AVC. The likes of Warner Bros which has pretty much entirely used VC1 will have to use MPEG4 MVC for any 3D offerings, and if they are switching over for that purpose, they may well decide it’s easier to switch for all their disc authoring needs.
