To be honest the reason I did not upgrade to EA controller was no 4k Video from CCTV.
In no rush for a new remote so will hang on until we get Geo fencing and 4k Video
3.3 is pretty stable and the Colour Wheel was great add on.
Just a guess, will the EA Controllers be EOL next year - Now the Core has newer faster processor and the new features will be designed for the CORE
