I think if Panasonic wants folks to jump ship (or come back) they need to make a real C100/FS700 contender in APS-C, not another version of the DSLR with M4/3rds.
This would mean a whole new line of lenses and possibly a new lens mount, which seems very unlikely. I don't see Panasonic partnering with Canon or Nikon for a new camera line, and going with Leica lenses would probably price them out of the prosumer market. PL mount lenses would also be cost prohibitive, though you could rent anything your heart desired.
This is why I expect Panasonic to stick with the Micro 4/3 format for prosumer shooters, and introduce PL mount cameras for working pros who can afford it.
