This will probably the end of the shared continuity, it was nice why it lasted. I actually feel depressed. Seriously, is this normal?
No. Most people don't get depressed about the speculation regarding fictional universes.
But in the event that Marvel gets the Star Wars comics license back--and that's not necessarily an automatic given, IMO--the worst-case scenario is the creation of a new
shared continuity. Marvel knows what Dark Horse has done with Star Wars, and I think the odds are good that Marvel would want to duplicate that. Marvel did go nine years and more than a hundred consecutive issues the last time they had the license.
