Has anyone else noticed that there are dozens of movies getting the ax from lineups, that would earn billions in the box office if they were made, and they are all getting getting chopped for no real good reason?

EXAMPLES:
Spiderman 4
Freddy vs. Jason 2
Kick-Ass 2
God of War: Part 1,2,3 (movie based on first game)
Gears of War
Devil May Cry
Resident Evil movies based on the games
