Will Halo 5 bring out infection in the arena

Just wondering if Halo 5 will introduce a halo reach style infection or a Halo 4 style infection or any infection game type at all for Halo 5. Very curious about this because infection has been a halo community for a long time and is required for making many AMAZING game types. Personally I think halo will lose some players if infection is not made for Halo. But what do I know I only played halo reach infection for 3 years and made it to a noble.
