This may sound crazy, but bear with me...
I noticed something odd while messing around with the charts just now. The original Ninja Gaiden Sigma (109 weeks old) sold 2,892 copies last week worldwide compared to 1,169 for Ninja Gaiden II (58 weeks old). This is without tracking in Europe for Sigma.
Then I looked at lifetime sales.

940k for NGII

540k for Sigma (could be over 800k with Others sales)

So, do you think it's possible that Ninja Gaiden Sigma 2 on PS3 could outsell the original Ninja Gaiden II on 360? I actually think it has a good shot.
