I would bet that the purchase and manufacturing/assembly costs of a pentamirror and mirror dimensioned for a 14.8x22.2 sensor + a dedicated entry-level autofocus module are lower than or close to the purchase cost of an entry-level electronic viewfinder whereas the purchase and manufacturing/assembly costs of a pentaprism and mirror dimensioned for a 33x44 sensor + a dedicated autofocus module is higher than the purchase cost of a mid-to-high level electronic viewfinder.
I wouldn't bet before knowing all parameters. There are too many unknowns. The volume may drive it in one way or the other. Electronics cost versus make & labor to assemble. The phase detect pixel you need on a MILC versus the module costs (e.g. AF) on a DSLR etc.
Initially they would have artifically high prizes to compensate for the loss in numbers of the reducing market i.e. technology introduction. Sony and Fuji add the lifestyle factor in addition. But the market pressure is so high, therefore is competition, these margins will very quickly come down.
Anyway, the camera is the smallest part. When I saw the cost for these new high end lenses, the DSLR will win. When reading the R mount or Z mount requirements, high grade lenses will cost more compared to DSLR lenses. Asnd the technology benefit appears small to me.
