Sadly, HK have said that they're prioritizing Armed Forces/LE for the 433, and they really seem to have placed all the eggs into the German Army tender basket. Granted, I'm fairly confident at this stage it'll be the 433 or nothing. But as to sticking with the 433, unless someone has more to offer about it, we don't have much to talk about. I'd be nice if the German Army or HK would give and update or if the trade shows like IWA/Enforce Tac didn't get postponed or cancelled.
Only "new" things I found about the 433 are actually year old photos from IWA last year that I didn't find before. But they're small sized and don't really show much of anything new. I can post them or links to them if anyone wants them, but beyond that, I don't have anything.
EDIT: I'm going to go head and post the images now before I lay down for a while.
