@EvilGeniusRo Thanks for being quicker and posting videos with EN subtitles 
I got the M3 concept info from the very same interview, and as far as I know, he hasn´t mentioned anything anywhere else. The other interview/stream I didn´t watch (it´s almost 6 hours long), but he mentioned the thing about Henry in a FB post regarding the M1 remake as well.
One of the saddest bits from the M2 cuts for me is how they gutted the Sicily mission. There was meant to be so much more… (apology, the video is only in Czech, but you get the idea - if necessary, I can translate it…)
