I think there's enough room for doubt to fathom the concept that it's not Oberson. As I posted on another thread, I think it would be silly for Telltale to go through the trouble of introducing this guy and build him up as a sick leader only for him to show up dead with no relevance to the main plot.
He could very well still be alive and any resemblance between the zombie and Oberson could be a result of Telltale using similar designs to save on time (maby even to misguide us to think there's no way it could be Oberson). Unless he's just one of the contest winners, I see no reason why Telltale would bother establishing him without an integral meaning to the plot.
Nice job on the list by the way, it's very well done!
