http://forum.shrapnelgames.com/showthread.php?t=50717 I've uploaded some early pics of new platforms.
Here are additional T-14 pics.
There're few things that can be taken as certain (or rather estimated) about this construction.
First and most important - 3 men crew with unmanned turret. The crew is housed in a compartment separated from the rest of the hull, especially from the ammuniton storage.
Gun - it is a 2A82 125 mm or some modification of it. 152 mm was rather shelved for now. There're rumours ciculating on polish forums that Armata could be using some new ammunition, based on Grifiel 152 mm family.
Weight is estimated between 55-60 tons.
Engine - possibly an A-85-3A or modification of it (power estimation - between 1500 and 2000 hp).
New active protection system - Afganets (softkill and hardkill).
FCS, visuals - unknown, with rumours of gsr use.
