I don't think we should start speculating about T-95 yet. There are not very many infos about it.
There are some speculations about the M1A3 too. And it is defenitely needed.
Give the Abrams fleet a new smaller diesel powerpack, a lightweight 120mm L/55 gun, new optics, an upgraded FCS, an autoloader (Without going from 4 to 3 crewmen), one or two RWS, active and passive protection systems and network it. With these upgrades you are going to enhance its capabilities in a big way without the need for a totally new vehicle and without hoping for any big technological breakthroughs.
FCS is in my eyes not dead but we are for sure not getting to see them as soon as expected and I am sceptical if they will be able to reach their targets. How much of the revolutionary tech needed for FCS program is ready yet? Was it under 10%...?
Just have a look at NLOS-C. What advantage does it offers compared to modern SPHs around the world despite strategical mobility? Nothing. It is in fact inferior to them.
I like some of the ideas of the FCS family. Highly networked, integrated UAV capability, common parts (Easier logistics/maintenance), advanced active and passive protection systems, etc.
But I don't see them staying with the weight restrictions IF they want to get highly protected and mobile vehicles without compromising firepower.
They already skipped the C-130 requirement...
