Yeah, I read the original post too quickly and thought the poster was saying they wanted an OVF and an EVF option in the same camera (giving the user the choice to use either depending on the situation). Hence the need for the pentaprism.

Under that proposed system they would still need to manufacture pentaprisms and I was under the assumption this was the one piece Sony wanted to move away from for cost reasons...

No, they would not need pentaprisms. A pentaprism would serve no purpose at all without a reflex mirror, so the electronic viewfinder would still be necessary.

If the SLT mirror is taken out of the light path, the only function lost is phase detect autofocusing. A flipped-up SLT mirror would limit the camera to strictly manual focusing or a different form of autofocusing, such as contrast detect. If you're okay with manual focusing you can turn any SLT model into a mirrorless manual focus camera today by removing the mirror.

In order to do its job correctly, the SLT mirror also has to be bigger than a normal reflex mirror, angled differently, and constructed from different materials. These are presumably some of the reasons why Sony has not made the mirror easily flippable.
