800,000 would not surprise me.
Active subs are likely higher. May 25th is the last of the prepurchase free time. So their eps call of 1.3 million active subs seems fair.
I am an active sub, courtesy of the free time given. I hardly log in at all, and won't after the 25th. I will, however, re-up from time to time.
Game has not been the best investment by EA, for the time and money involved, and Lucas's fee.
