Forge/ custom games updates in the future?

[Nachoabyss]

Can anyone confirm if a forge/ custom game expansion/ update has been announced? (new maps, new settings, new abilities/ functions, additional items to forge with, return of the elephant or hornet, etc)

What improvements to forge/ customs would people like to see?

Also when will the file share/ map search function be completely up and running?

These are questions on the mind of all of us, but there have not been any answers.
The closest thing we've had to answers for this is the most recent Halo Bulletin, which states that there will be forge maps going into MM soon.
