[EVERYTHING] Cersei or the Wight walkers?

So up until this point I've been thinking that the show will eliminate one big threat at a time starting with cersei this season and the the wights next season. But now to me it looks Ike the show might be switching the two and save cersei till the end witch makes sense to me but I'm not sure if I like it. Does anybody know if the show has said anything or if somebody has already debunked it? I haven't found anything discussing this but if there is can somebody share a link to it?

Summary: will the show kill the wight walkers before cersei?
