Halo has a total of 12 game installments while CoD has a total 15 main game installments (this means not including games like "CoD Online" or others titles specialized for lesser systems like handhelds). Halo is undoubtedly a younger series, but I don't see a very large gap between these two. That is beside the point.
Do you think they will stop at Halo 5? If no, what makes Halo and CoD any different?

Halo? A younger series? Considering Halo CE launched in 2001, and the first CoD game came out in 2003... You see, the difference is that they don't reskin Halo and sell one to two games for Halo every year. That's why there are less Halo games.
