BMCC Ef Mount Future

I apologize to those who don't really dwell on speculative issues but the hot thing on the MFT and Sony side of the world has been without question, the metabones speed booster. Granted the product is relatively new (though the technology isnt) it makes me wonder about the future of the EF BMCC.
If the Metabones MFT fixture proves to be as good as the Sony E Mount (and many believe the MFT version will perform BETTER) it effectively reduces the value of the EF version compared to an MFT (or active mft) version. Especially with the EF flange issue and infinity focus problems.
I wonder if the EF version will slowly be produced less and less with the MFT version being the flagship option. Which I certainly hope so.
