I’ve never heard a plan to support 2.4 GHz - considering the hardware of both the original Bond Bridge and the slight revision / newer Bond Bridge both lack any GHz support, it would have to be a new hardware revision Bond to be able to support those.
Where did you hear that support for 2.4 GHz (or any GHz) was coming soon? I’m sure the Bond team would like to correct them 
As far as I know, these are the only supported frequency ranges:
New revision Bond Bridges: 285.5 - 505.5 MHz
Original revision Bond Bridges: 300 - 450 MHz
