This question came up on the Dead Rising non-wikia wiki:

Kirkman did tease something about the season 3 premiere as he mentioned that just because Dale died in a different way than his comic counterpart doesn't mean that that death couldn't be in store for someone else:

"There will be cases where something memorable like that will be displaced and given to somebody else. I'll hint that that actually happens in our first episode back in Season 3 — there's something memorable that happened to a character in the comic is happening in the show in our first episode back and it's not the same character."

In the long-running Image [comic] series, Dale winds up being bitten by a walker, kidnapped by cannibals and having his infected leg cut off and consumed before being set free and dying at Andrea's side.[1][2][3]

So what tragic event is Kirkman really refering too?

So What has not happened in television series yet which happened in the comic? Any guesses?
