I think Neville will definitely play a big role in the final book -- he will be involved to help HP as much as needed because it is thanks to LV (in a roundabout way) that his parents are how they are today. Part of Neville will always want to get back at Bellatrix and the DE's in general and since the DE's obey LV's orders, he has a valid reason for wanting to support HP as best he can.
I forget now, do we learn exactly what Luna's mom was working on when she died? Perhaps it was something against the dark arts? And if so, Luna, too will have reason to want to be there as much as possible. But that might be a stretch I guess. I think Luna, perhaps for no other reason, will want to be involved because she now knows that HP, et al, are her friends. She has never had true friends before. I'm guessing one of Luna's main characteristics will be her loyalty to her friends.
edited to add:
forgot to mention...I also think Luna and Neville will be coupled off at some point.
