Yes, a good news story for such a historically significant - unique - group.
Nonetheless, to play devil's advocate; while possible - it is not by any means certain, that the the group would be split if sold to US collectors. As a US collector, I find that part of the article just a bit disingenuous. Just because the items were physically located in the US doesn't mean British collectors - or German - or any nationality - could just as well buy and split the group given the world-wide nature of auction houses etc. Why not just say "collectors" in the article without a modifier?
And even then, I think it's not certain it would be split up; I would expect the price tag would attract a true collector from anywhere in the world who wouldn't even think about splitting.
But that's not the most salient point I'd like to make - it's a double-edged sword for us, isn't it? We see this as good news (and again, I agree in this case it is); however, if families didn't offer their ancestor's awards for sale we'd have almost no hobby would we?
