Since season two covers four years of time, versus the one year covered by season one, it at least looks like it will have a smaller amount of boring filler.
I don't really want them to twist the show into a pretzel to accomplish this, but I would love it if the "this is a Rebellion, isn't it -- I rebel" line that appeared in the Rogue One trailer but not in the actual movie could make its way back into canon. In a franchise relatively low on badass lines, it's a shame to leave that one on the cutting room floor.
