In terms of players playing, it mostl likely will as it is the 4th Halo FPS Installment from Bungie. But, just like other installements for other franchises, players still play the previous installment as well.
A perfect example is Call of Duty 2, Call of Duty 3, Call of Duty 4, and Call of Duty 5.
A major drop in players comes when the most recent installment is on a more advanced platform that is currently supported.
An example would be Halo 2 on the Xbox compared to Halo 3 on the Xbox 360. Actually 5th.
1st: Halo: CE
2: Halo 2
3; Halo 3
4: Halo 3: ODST
5: Halo: Reach
