Reminder - 2K5 outsold Madden.
I keep seeing reports pop up about how "2K couldn't outsell Madden when it had the license". That's not true. NFL2K5 outsold Madden, and shortly thereafter EA bought exclusive rights to the NFL's properties in video games.
It's also little coincidence that NFL2K5 was $20, and a better game. If/when a price drop comes down, I would expect to see people picking up APF2K8 that might not have done so otherwise. These additional sales may be what makes the difference on whether or not we see a 2K9. Keep in mind - football season hasn't even started yet, and the Christmas season is still ahead of us. There are still plenty of sales to be had before the fat lady sings on this. It's just not really worth debating right now.
