Yes and no. The M1A3 is part of the NGCV project.
The NGCV can be split between vehicles that are in service, or close to entering service, and vehicles that are only in early stages of development. All these vehicles are included in the NGCV because the Army plans to incorporate some of the core technologies developed in that project, into every AFV. Whether the vehicle is "new" or "old" only affects how much of the less important and more peripheral tech can be added as well.
So in a way, they DO have some definitive plans for the M1A3 Abrams, and you can pretty much guess them by following the requirements of the OMFV. The process is similar in Israel and Germany+France (I assume, because the european project is still under wraps), where a unified architecture is pursued for multiple vehicles at once.
So my take on it is that the M1A3 is very likely to have:
2)automatic and unmanned turret.
4)automatic cuing to target.
5)multi-sensor pre-firing and post-firing target detection.
6)automated target recognition.
7)360° vision system.
And perhaps I'm missing a few. Overall can be seen as very similar, if not identical to Carmel. It could be that RAPAT and CCDCGVSC (formerly TARDEC) are cooperating on requirement setting and technological demonstrations. First physical evidence for that was a substantial American presence during the Carmel's demonstrations.
It was said, I believe around 2016-2017, that a new M1A3 might have a 3rd crewman to operate unmanned or special systems. If so, it does not yet mean the 2 man crew part is untrue. The Carmel is also said to have a 2-man crew, but in every demonstration video it was shown to have 3 seats, with 1 belonging to a person that may not be present at all times. That is, you can expect the M1A3 to drive with a core 2 person crew, and in certain missions where unmanned vehicles are required, a specialist will enter a special station in the vehicle and operate the systems.
After reading the same about the Carmel, I've hypothesized it could be just a special version for the platoon commander level (and above).
Alternatively, a special drone operating crew could hitch a ride on a recon unit's vehicles.
