Earlier in the month, Herbert Keppler from Pop Photo asked them point blank if they were going to use the KM hot shoe and got no answer, yet they say in the announcement that KM owners will be able to use their lenses and accessories with the new DSLRs. Hopefully this will include the flash units. It would make good sense to use as much of the tehcnology that they paid for as possible.
Sony has announced that they will be using the same lens mount as the Konica Minolta DSLR cameras.
Looks like Sony will be releasing a DSLR camera under their name and you will be able to use your Konica Minolta lenses on it.
