Nokishita Camera just found that the upcoming Canon EOS-1D X Mark III has already added Canon’s latest product lists. This means we will see official announcement of EOS-1D X Mark III in next few weeks. Most likely at the end of January to early February.
From Nokishita Camera:
“EOS-1D X Mark III” and “WFT-E9” are added to Canon’s latest product list. It may be added early because it is the year-end and New Year holidays, but reservations should start within a month if usual.
