What publisher Square Enix will not confirm that developer Avalanche Studios is working on a sequel to Just Cause 2, we believe that the recent domain registrations for Just Cause 3 and Just Cause 4, that there is a good chance that something is up.

Sources say that developer Avalanche Studios has been working on something called Project Mamba, but we told that they are unsure if this is actually Just Cause 3 or a futuristic Mad Max like title that the developer had previously referenced back in 2010.

We tend to believe that an announcement for Just Cause 3 from Square Enix is just around the corner at E3. If it does not happen, the we known for sure that they are going to tell us exactly what it is that Avalanche is working on.
