I don't believe there will be any content influenced by the upcoming movies. You need to remember that SWTOR is THE OLD REPUBLIC. If you follow Star Wars especially the Expanded Universe, the Old Republic takes place thousand of years prior to the current episodes. Luke and gang were not even a glimmer in anyones eyes during this time period. If SWTOR went with current movies influences then they might as well re-name the game.

I think your suggestion is a great one. I tend to be a soloist and do not want to join a group but still want to accomplish a op. or flashpoint. Especially for HK-51. I have completed everything except the group missions such as FP and Foundry. If not having 3 companions with you, why not have the flash points equate to your group/level. Or for special quests such as obtaining HK-51, why not have alternate quests that take longer to complete but can be done solo? Not everyone wants to group or PVP but everything should be accessable no matter what your playing style is. Just make it tougher for soloists.
