Since this game is back in development, we may (or may not) have a last chance to put in our own 2 cents on concerns we have for the game before final launch. I have recently been playing The Lord of the Rings: The Card Game and it has raised some concerns for me about the new Star Wars game, especially looking at how many players are complaining that it's broken. I have 2 main concerns.
1) This game will be a carbon copy of LotR. I think the demo pretty decisively showed that's not the case, but I hope they're not going back through the game in development and making more and more like LotR. An extension of this is that even if gameplay is significantly different, they might end up using the same encounter deck ideas for SW as for LotR. Again, this doesn't seem plausible, but I'm just emphasizing that I want to see some new stuff. For example, I don't want to see Force Pack 3 be an escort mission of a damaged Rebel dignitary's ship (i.e. Journey to Rhosgobel copy).
2) My second concern is exactly the opposite, I hope that the effort to make these games similar doesn't end up causing the development team to throw out things that work really well, just because they're trying to keep it fresh. For example, an escort mission is a really good idea, I would just like to see it in a later cycle, rather than the first.
