Anyone saying it will do reach like numbers is dead wrong. Even 3 million fw is high. Of the 1 million pre-orders probably 750k did so to get into the beta. Those 750k people were going to pre-order it closer to launch(most in its final weeks). So as a result the coming 19 weeks and especially the last few weeks wont see huge numbers. Id say 2.5-3.1 million fw ww sounds about right.
i know its the fastest pre-ordered game ever but had reaches beta been accesed by pre-ordering the game instead of having odst i think it would have been at 1.75 million pre-orders at this point.
