Best answer for anything without a definitive date like this is "SoonTM". Though, I'm pretty sure that you shouldn't expect it to return in the same exact format as it was before the removal, which personally for me is kinda sad, though it's more out of nostalgia than anything lol.

There's not a definite ETA yet, but I can at least reassure that there will be upcoming Umbra (confirmed by DE themselves). Not sure about Umbral mods though.
