Prediction: Succubus Eye is probably a set up to stall Fairy Tail while the Oracion Seis regroup and then them and Tartoros do something evil. (yes, i know they regrouped in the anime,but not in the manga. i had this theory cos of what cobra said)

Natsu finds and eats the eternal flame and transforms into a new form or beats succubus eye.
