New concept Rosomak-M vehicle increases payload, firepower and amphibious capability..

I've been digging all morning to try and get info on this vehicle.  No joy though. It sounds like the work that Lockheed Martin and Patria did on the USMC Amphibious Combat Vehicle project is not going to waste.

Is this the new standard Rosomak?  Have the Poles suddenly solved their swimming IFV issue with a new buy/upgrade (if possible...I have no idea whether existing models can be upgraded to the M-model or not).
