FX UK have launched new character profiles for TWD Season 3. Most contain things we already know but some seem new, for instance:

-Beth and Carl become closer (possibly a new Sophia?)

-T Dog brings humanity to the group

-Carol gains a sense of humour (beieve it or not)

-Lori and Rick are not on speaking terms

-Merle is the Governor's second in command and he will have to choose between Woodbury and Daryl
