Link here for more pics of the prototype.
I have no idea why they boast the fording capability that much, they could just as well advertise it as the First Nuclear-Proof Tank due to the neutron liner...

Maybe what is to be understood by "
the gun turrets can go underwater" is that the main gun can fire immediately after surfacing, without needing to be emptied/dried/cleaned/whatever. I don't know how exotic that is though.
Apart for that, basic tank snorkeling as far as can be seen.
The defensive suite looks
much more promising if all the components can be purchased for the series version: turret-top ERA, hard-kill device, BIFF...
Also the FCS should be largely on par with the latest Western designs.
Now let's just lean back and see how the ROKA is going to fund this one...
