RE: 12X
Pointless asking just yet as it is not at a production stage. It is still in design and probably will be for a while yet.
Please remember that ALL distributors get sample models at roughly the same time so that they can give feedback, allow for FCC / CE testing etc etc. Then it will go into production in batches for the market (ie a batch will be made for 40 MHz, then 72MHz, then 35MHz, 36MHz [ but not necessarily in that order]).
Remember that Horizon did NOT take the 9X when it first came out but developed in conjunction with JR the 9303 which was then re-released as the 9XII.
