Wow this is big news. I'm sad to hear that you're leaving after so many years of work, but all good things come to an end.
I hope that the FH2 team is able to find an able replacement, and I hope you perhaps help them with that if possible. As you said, the team is getting smaller and yet they have so much content yet to complete on this epic project! Now is as good of a time as ever for all of us to call out and try to get talent interested in working on this mod.
I for one am dying to see the Eastern Front, but it won't be possible without talented and dedicated bodies like yourself on the team.
