Surprise!
This is no Leopard at all - Rheinmetall left the franco-German MGCS project (Depending on who you ask, its called "Leopard 3" or "Leclerq 2"), because it didn't have much influence on the result there. Looks like the French gun won there, so they produced their own tank around their Future Gun System and presented it today. Has a three plus one tank crew, with the loader replaced by an autoloader (because of the heavier ammo, ~20 MJ projectile energy), but a fourth seat still being in the tank hull. The fourth seat is planned to be multipurpose: It could host a company commander or aides for him, or a weapon system special, possibly for controlling UAVs or fighting UAVs with the remote controlled gun platform. It is possible to equip the tank with Israeli HERO loitering ammunitions. Tank commander and gunner are still in the turret (A T-14 like solution with all the crew in the hull would have been unlikely after the really bad German experiences with such tank designs in the 1980s and 1990s), driver in the hull..
Right now, it has a lot in common with the Russian T-14 Armata tank: Its just for show. While this looks fairly complete as it is presented, it is likely far from complete inside. It is equipped with a Frankenstein-like collection of many Rheinmetall products. Understand the surprise presentation and the press release as a loud reminder to the German government to do their job.
Anyway, despite the inner German politics, the product vision is actually pretty nice. Its tank design is as conservative as possible for a next generation tank, despite all modernisation and without the Leopard 2 heritage, its at least possible to have addressed its weaknesses. The 130mm tank cannon and its ammo aren't NATO standard yet, so its not very useful, but it was planned to do that anyway. Even if the governments of France and Germany keep the MGCS project, its possible that this tank gets a intermediate role in NATO by the other smaller countries.
