I dont know if what your saying is true with madden sales from PS1 to PS2 declining. Proof would be needed.
Anyway when the boss of EA has a article stating that he is very upset on the fact that Madden 10 sales are low. I think that is a pretty good indication that things are bad.
I have made 2 predictions and all came true.
Madden 10 would not sell well. Posted in Aug 08
MW2 would break records in sales Posted in Apr 09
My next prediction. Madden 11 will not sell well at launch, but will improve come September/October.
I say this because my gut is telling me that 11 will be greatly improved, and it will take about a month to convince those that left the franchise time to believe.
This is coming from someone who has not bought a Madden in the next gen era period. I play the pc version of 08, but that flame has dwindled.
Anyways I'm hoping to be 3 for 3.
NBA Live got me back so why can't Madden.
