The upcoming Canon EOS R5 now officially registered at Bluetooth Certification. This means we will see EOS R5 released soon. But due to coronavirus, there could be a delay for EOS R5, as EOS R6 has been already delayed.
From Nokishita Camera:
Canon “DS126831 / 36/37/38/39/40” also passed Bluetooth certification. Probably all “EOS R5” (36 is North American version [1-11,36-64,149-165ch], 38 is Taiwan etc. version [1-11,36-165ch], 39 is Chinese version [1-13,36-64,149] -165ch]. There should be a Japanese version [1-13,36-140ch] and a 1-13,36-165ch compatible version).
