Halo MCC - Flood firefight?

Sooo months ago I played the flood firefight flight and it was pretty cool, despite the bugs and being unable to finish matches(some flood marines would go off about their business and never return) but it was still great, along with the elites added to ODST.
But where is it?
343, promised to bring it to life and well now… there is 0 news about it!? Come ooon, I understand you guys are trying to fix infinite(3/10) but this was something everyone wanted since ODST originally released. And Bungie would never do it but you guys(343) have a pleasure in teasing your community with false promises. Again and again. MCC is great, now and I suspect Infinite will take the same amount of time to fix… so why the hell not finish it? Give me some news maaan​:disappointed::disappointed:

343i have already said that the delay was due to bugs with the AI (which you acknowledge). It will be released in a content update sometime this year.

The silence is what kills me

I’m just gonna be in denial until they “say something relative” and not so “vague” per usual. Or am actual update.
