A new figure of Alice ver. Boost, though it seems a preorder-only limited edition.

Edit: The QB Rebellion anime
will have 6 DVDs, that will come with short "restriction-smashing" OVAs for different characters and various other goods.
Edit2: While on some small research to fix the Wikipedia and stuff, I found out that Melona has a new title for Rebellion, the "Protean Trickster". That there basically confirms a future book for her (if the returning chars we already know ever get a book), and I'm willing to bet we get her new profile in the upcoming 3rd Illustrated Stories volume, along with the Witch's, if not earlier.
