Just ordered Vero 4K but have been thinking about this too. My issue will be that I won’t be able to use my Samnsug TV remote to control Kodi as the Vero will be hooked up to my AVR -> TV etc.
I currently run an Rpi3/OSMC hooked directly to TV for TV shoes but for BluRay rips I have an old(ish) HTPC with 2 HDMI ports, one hooked to TV and one to AVR. That way i get both surround sound and CEC remote. Reason for buying Vero 4K was to replace the HTPC & RPi3 so CEC remote not working is going to be a pain. Also, wanted to use Vero for everything and ditch the Rpi3. For TV shows, I dont need surround sound so 2nd HDMI to TV would have been perfect.
Will see how i get on but 2 HDMI ports would be awesome. Otherwise will probably get a new HTPC running Intel 9th Gen as and when.
