What could happen in Amnesia 2?

Yeah, uhm, I'm pretty sure Herbert died very soon after finding the orb.

nope

"2nd of July, 1839

I received a letter today from the Algerian Governor's office disclosing the fate of Herbert's expedition. About a week after my departure Abdullah, one of the men traveling with us returned from the desert. He was badly injured, as if maimed by a lion. The man rambled, deliriously, about the expedition being attacked by something horrible. The French quickly dispatched a search party to look for the expedition. After searching for days they found the camp abandoned, without any traces of Herbert or his men."

I think it's pretty clear Herbert and his group are dead.

no, missing, therefore you are wrong.
