The front of the unit resembles a flash body. Its unlikely there will be any AF assist light behind the red lens though.
The base of the YN560-TX shows a metal foot with locking pin and full Nikon ETTL contacts. Though these are likely only for the flash wake up feature as the RF-603 II etc have.
The YN560-TX will support all the major functions of the remote YN-560 III flashes in up to 6 individual Groups.
Powered by 2 AA batteries, the YN560 TX For Nikon very much resembles the body of the YN-560 III flash unit. Though its considerably narrower and would be much lighter.
Provided the specs have not changed, the YN560-TX should be compatible with any camera which has a standard hotshoe.
