Now these 2 answers by themselves don't mean much. But when put one after another, with a reference to the first one in second answer (the word Also), it is very likely hinting that Illidan will in fact return in the Sargeras expansion. Not 100%, but this is the feeling that I got when reading these 2.When...Will...We..See..Sargeras??
You are not prepared.
Any chance we will see Illidan return soon?
Also not prepared.
