A new trademark filed with the European Union for Bully Bullworth Academy: Canis Canem Edit has some fans excited that Rockstar Games might be planning a sequel to Bully. In addition, the "Bully" trademark was updated back in July in the United States.
Rockstar has merely told fans of the series to stay tuned for news on any new developments of the series.
The possibility of it being a sequel is quite high given that the original came out in 2005 for the PlayStation 2. Then again, perhaps it's another re-release, like the one that came out in 2008 for the 360 and PC, or perhaps it's an HD remake. Whatever it may be, it's certainly not Red Dead Redemption 2 nor PC versions of either the first Red Dead Redemption or Grand Theft Auto V.
