Theres no absolute proofe he did, but the technology Wesker created didn't invlove cloning tech.I mean he speant years combining the T-virus, the G-virus, the T-Veronica virus, and las plagas parasite to create Uroboros. Not to mention being controlled by Spncer. So I'm sorry but unfortanatly Wesker dead. Capcom will probably only make Resident evil games that are prequal to the the story line. Infact there making a Resident evil Darkside chrinicles which is a remake of Resident evil 2. Resident evil has had a long 13 years, but like many other commpanies capcom's time with Resident evil needs to move on.
