FLOOD and ELITES in firefight?

¿Hi how are you? I wanted to make this topic because i was really wondering if the flood and elites will be added to halo mcc firefight,
we had a preview of what would look like playing against them and it was cool
so i was wondering if theres any chance that we could get them in the comming months at least for a last content update to the master chief collection and if not i really wish 343I could notify us because its been 4 months and we really havent heard anything about it.
