It looks like RS has a report up showing that some previous
Battle Packs are making a return in the Legacy Collection (not that they need to):
Clone Attack on Coruscant
Jedi vs Darth Sidious
Jedi Training on Dagobah
I guess these are good sets for kiddos or new collectors, but they've all been out fairly recently so I'm not sure if it is necessary or not. I won't be picking any of them up personally, but I always kind of thought the Dagobah set was kind of neat. I would have liked it as a kid (or if I didn't have the figures included). A nice Obi-Wan and Yoda, a decent Luke, a Vader, and an R2 repaint. Now if they'd just put out a Dagobah playset to go along with it
