This tidbit of info comes from a member (AKA: raz) on a Power Rangers board:
As you can see, it says Spider-Man, Avengers and Batman are the big sellers. Followed by Beyblade, WWE and Power Rangers bringing in a steady stream of dough.
TMNT is expected to be big. Roleplay and interactive items seem to be helping sales.
Transformers is mentioned nowhere on there, good or bad, but chances are they fall into a negative category. Most stores, aside from TRU, have no stock of TFs right now and won't restock for at least a month.
