Do you remember the picture with the FrSky branded transmitter in the background? Now this transmitter, called FrSky X-Lite is not a rumor anymore. It is a game controller form factor transmitter with high accuracy hall sensor gimbals, OpenTX operating system, 128*64 LCD display. This TX supports external JR/FrSky modules, has miniUSB microUSB, SmartPort and headset ports, also a microSD card slot! We dont know yet will it support voice features or will it have only a buzzer. Internally this transmitter will have the same iXJT RF module as in other Taranis models.
Even more, this TX will have a batery bay for 2x1865018500 LiON rechargeable batteries with an easy-access door. A plenty of work hours between recharging!
So basically this TX has most of the features that Taranis series transmitters have, just in compact form factor and even more. Hall effect gimbals lift this transmitter into higher grade.
Unfortunately the final price is not known yet as well as no estimated date of availability on the online stores. The rumored price is ~120USD.
Update 2018-02-01: there is a picture of thr FrSky booth in the german toy expo with X-Lite transmitter and FrSky tricopter called Rover-3.
Picture of the back of the transmitter. Looks like some mini sized external module bay:
