Personally I'm not too sure you know, but I don't think it will...
Don't want to be too negative, but sometimes I remember this site exists, and it was kinda dying off once there was a platform divide back when MCC dropped on the new Xbox One (Project Scorpio still sounds better fight me). Some people couldn't join in on some of the community events because they didn't upgrade, and with the flop of Halo 5: Guardians, I think a lot of people just sorta drifted away into new games. Community events started to dry out and we'd be lucky to get six people for an event and at that point we might as well just play multiplayer.
Now that the page isn't listed on the first page of Google, unless we plugged the hell out of this forums or got the site's overall views up to at least first page worthy, I doubt things will improve
Whilst it's true this community may not return to it's previous activity, or even near, the Halo community in general hasn't been this active for a long time. I wouldn't say many drifted away into other games for good, possibly just temporarily. Many are returning with the good news of Infinite, and especially with MCC + Reach coming to Steam (and simply Reach being added to Xbox One). I know many who are looking forward to that, some still playing Halo regularly and others not. Halo's saved, and more, the fate of this site remains undetermined though.
