Figure a reasonable price and double it.
$599 X 2 + $1195 for the kit with 22mm lens and M to EF adapter..
You think they can make it 300$ above the T4i kit and a 100$ above 60d kit?
Looking at initial poll votes we can see, how unpredictable this product is
Very possibly. If the G1X is priced at $800, the mirrorless APS-C with interchangable lens ($200) plus M to EF Adapter ($200) will cost a bundle. I do not expect a body only version, since a lens or at least M to EF adapter is needed and no one has any lenses that fit it right now. I would not consider a body only at first.
Compare it with other Mirrorless Cameras, not DSLR's. Thats why Canon is releasing a mirrorless, they seem to be made of gold, and Canon is not going to let Sony or Fujii out price them. Unfortunately, Nikon 1 with its tiny sensor V1 does not compete.
