The most interesting thing is how the Rogue One story is connected to the PT era:
For years the Republic and the Separatists have battled across the stars
Could be fun if LFL decided to produce a Clone Wars story arc based on this new material regarding the DS construction near the end of the conflict. A slight temporal weirdness of ROTS could consequently be corrected. But still, the CW during only 3 years and a few months always seems a little bit short for me.
