I wouldn't mind seeing the other guilds because we don't see much of them. Its not like they have there own series. Even so it's not like they would play a major part in the story arc. They'll just be there taking on the foot soldiers while FT takes on the big guns. Depending one how long the ST series is I think we'll see a increase in Sing and Rouge power levels the same way we saw in Gajeel and Wendy's. They are 3rd generation Dragon Slayers. So in theory they should surpass Gajeel, Wendy, Laxus, and Cobra.
