I agree with this, and don't really see any reason why this won't be the case. It's not like they're replacing all the LucasFilm staff, the only real changes are the fact that Disney now gets money from the Star Wars universe, and George Lucas has retired. I really don't expect that they'll just ignore all that's been done.
I don't think they will be that concerned with complying with the EU in the new trilogy. What us fanboys forget when it comes to things like this is that we're a pretty small group of people and when a company makes a movie they want to be able to make money on it which means appealing to audience bigger than just us fanboys. It means appealing to audience we are a mere fraction of. Working on coforming to EU continuity just so it works for that fraction is not going to be a high priority. Continuity will be sacraficed in the name of appealing to as many people as possible if necessary.
