As of this time it's just rumors about a Rebel Trooper (from the POTJ line) set for later this year.
I for one would love to see this set and I am sure that other collectors would buy it. I would love an army of troopers.
Just one suggestion: have different heads for the figures. That would make the set more appealing.
Also, consider a four pack of Death Star Troopers. This figure from the POTF2 line was very hard to find and I am sure many people would love to get not one but four of him.
