So how long does each season go for? Anything confirmed on that?
Ideally about three months with a two week lock before the reset. Three months allows for better division placement by the end, and a bonus pool that isn't so huge that unless you're constantly playing never have any hopes to churn through.
Season 1 ended up being about nine months, and in the hopes of simply not prolonging it any further, the lock is only one week.
There are variables that could dictate when new Seasons happen, but in general we're looking at new Seasons beginning approximately every three months.

Effectivement, 3 mois.
