Perhaps the new tank's cannon is it's pistol. It's rifle is in the rear in the form of ATGMs, long range rockets and artilleries.
If it has options to not engage with it's main gun in order to preserve stealth, then that's what it will do.
In the grand scheme of things, the overall concept with a 40 tonne weight and 2 man crew seated in the hull really do remind me of the US Army FMBT from The mid-90s.
