Spoiler Yeah, it's all over the official Reddit. I'm not sure it's much of a spoiler since Cameron stated that Quaritch would be the main protagonist of the sequels. And if you look closely, the avatar shares the same tattoo. A theory is that the original Quaritch himself was cloned and that he was psionically linked to the human body we saw? And that he's returning but this time in an avatar body to face Jake's family directly to weaken and demoralize them before going for more unobtainium.
