IF the Scout Trooper officially drops tomorrow then it's definitely conceivable we'll get a Star Wars reveal to go with it. Isn't that the way they tend to do things now, each property has its own dedicated day or week? Maybe wishful thinking. You'd have to think today and next Tuesday, at a push next Friday, are the last opportunities to reveal anything SW-related before May 4th. Anything after Tuesday and it's drawing so near to May 4th that they might as well just hold back.
Just doing a quick check on the dates of last year's releases and there was an April release, the Scout Trooper & Speeder on April 23rd. So, maybe one last Mandalorian release before May 4th. Mando Luke or S.3 Din would seem too big to release this early, so maybe someone like Koska Reeves or Fennec Shand.
