I don't think this view reflects what camera manufacturers are actually doing.
The
launch media conference of the Canon EOS-M mirrorless in Japan provided a number of interesting slides of the market strategy of Canon with mirrorless. It's clear that for them moving into mirrorless doesn't mean entry-level DSLR's are going to go away, nor high-end APS-C either.
Mirrorless is presented very much as a way to attract more people, especially P&S upgraders, into their lucrative DSLR segment, especially lenses. As the Google-translatese says:
"The company has explained that the lineup rather than the alternative of SLR cameras, expanding the market.."
Furthermore, as the 'pyramid' chart in the presentation highlights, mirrorless is meant to sit alongside entry-level DSLR's, and encourage people to step up to more advanced DSLR gear once they grow out of mirrorless.
