I would say no to Rogue being a final villain like some have said we are past this point and he wouldn't be all that powerful compared to Natsu, Gray, Maragane, ect.

I personally don't see Natsu/END as a final villain as END and Gray will have some form of a fight and END dose want to defeat Zeref anyway so he would probably be one of the last people who is going to be fought before the final villain.

I personally see either Zeref, Acnologia or Anhkseram as the most likely candidates for being the final villain as all three in some way or another overal have impacted the history of Earth Land on a huge scale in some fashion whether the characters realize it or not thus this is why I see the three of them as the best choice as the final villain overal for Fairy Tail.
