Actually, I think they're keeping The Spectacular Spider-Man because it is one of their highest-rated shows and they lose the rights to it in March, so they're just going to enjoy its high ratings while they still can. Although, it is nice to see it on the air still rather than have it disappear for months, even if it is the same 13 episodes over and over.
The question is, why is Will & Dewitt still on there. A promo on 4Kids.TV doesn't have Will & Dewitt on the schedule, though, and implies RollBots will replace it in February. Is RollBots going to be E/I too?
