We're just a few days away from the launch of this Haslab campaign. It's almost certainly going to be on Friday during the Hasbro Star Wars panel (IIRC it's at 2 pm PT).
I think the consensus within the community is that this is going to be the Ghost. But the questions remain:
What will the backing threshold be? The Sail Barge had a backing threshold of 5,000 units, and wound up with over 8,800 backers. The Razor Crest's threshold was 6,000 backers, and wound up with over 26,000 units backed. I think these are most appropriate comparisons for the upcoming campaign. The Black Series Rancor campaign was more of an example of what NOT to do.
What are the stretch goals going to be? The challenge presented here is to make it something interesting / relevant to the Ghost but at the same time something that isn't necessarily locked behind a $600 pay wall.
