SKYWARD SWORD SPOILERS BELOW!
I voted "no" on the poll, because I hope that the next Zelda game goes back to the series roots, story-wise; I hope for a game that goes back to the lore of
OoT and
AlttP, but that does not necessarily need to take place in Hyrule. However, any game that depicts the war between Hylia and Demise should include Ghirahim.
Ghirahim was a good villan, but I doubt that he will return in any
SS sequel, for it seems like he was killed when he became Demise's sword. Also, it would be strange if Link and Zelda ignored Ghirahim, should he somehow have survived.
