forging and the TU

With the news about the title update and all i was wondering will the forge see any changes?
Like would it be possible to have the ability to select actual full colors for objects or something along those lines? Or maybe the ability to add textures and things of that nature.

I hope that would be the case but I think it would be EXTREMELY unlikely.
And doesnt MS have a limit on the size of an update for a game? I doubt they could add any textures/objects in via an update that is limited to 5MB.
