Take a DSLR and remove the mirror and you get a “mirrorless DSLR”. Take a mirrorless DSLR and add an adapter that contains a partly-silvered mirror that sends part of the light to a Phase-detection AF sensor and the rest to the image sensor and what do you get: a strange mirrored mirrorless DSLR with fast Phase-detect AF.
Is this hinting at Contrast-detection AF reaching a practical focusing speed limit?
