Northlight has been told that the upcoming Canon W-E1 SD card style wifi adaptor will work on various Canon DSLRs. You can expect different levels of functionality depending on which DSLR you use the adaptor with.
We imagine there will be firmware updates coming quite soon after the announcement of the new accessory for supporting DSLRs. We had been told previously that a firmware update was coming for the EOS 7D Mark II, but we're not sure if there's going to be any features added beyond bug fixes and support for the W-E1.
