In what seems a strange move, Square Enix has registered several domain names for Just Cause 4. Why is this strange? Well because Square Enix and Avalanche Studios have not said anything about Just Cause 3 apart from a few rumors.
According to Fusible.com, Square registered the following domain names JustCause4.com, JustCause4.fr, JustCause4.co.uk, JustCause4.de, and JustCause4.it.
This action may lead to a reveal of some kind by Square Enix and Avalanche or it could just be that Square has taken up a preemptive with these domains.
