That's plausible, but some of those characters are from some very recently released expansions. Do think it was exactly between the time when that those expansions and Rebellion were being planned that the edict of Disney appeared?
Totally true, the latest X-wing, Armada and IA stuff all have 'old EU' stuff appearing. I'm not sure what the design cycle for any of the Star Wars stuff is, but I suspect the lead time for the minis-centric stuff is pretty long, so maybe these were all started long enough before the 'old/new EU' divide was set in stone that they were grandfathered in.
Anyway, I don't pretend to know all of the details. I just know that FFG's job got a lot more complicated.

They've said (somewhere, I can't recall) that their cycle is 18 months. So, the stuff coming out now should have been forming in their brains in the summer of 2014. The Lucasfilm Story Group started operating in 2013, and they ditched the EU in April 2014.
So, you might be right that we're seeing the last vestiges of the EU (some of which is really coming from the bottom of the EU barrel) before the axe came down. But at the same time, the LSG could have put a stop to FFG's production cycle at any point, saying: "Change [that] name into [this]". Also, they might have had to go to the LGS for clearance on any project since the formation of the group in 2013.
At any rate, I think there's too little information to be sanguine one way or the other.
