I'mma put it out there right now: Midna was more annoying than Navi and I don't want her back unless she stays in the background as a story character and doesn't join you on your quest. The basic summary of why I hate Midna? ...
Midna: "WOAH WHAT HAPPENED, HERE? THIS IS VERY STRANGE! YOU SHOULD PROBABLY GO AND CHECK IT OUT, SHOULDN'T YOU? ... *a pause* WELL? WHAT ARE YOU WAITING FOR? GO CHECK IT OUT!"
Me: "Gee, Midna, I
might go check it out...
IF YOU'D SHUT UP!!"I hope she, nor any other helper, for that matter, show up in Skyward Sword. Ocarina of Time, Majora's Mask, and Twilight Princess pretty early on in their development revealed their helpers: Navi, Tatl, and Midna, respectively. I actually think I was on something of a video game hiatus when WW was revealed, so that one I didn't know much about from the beginning, but that one had no strict helper, which is one of the main reasons I love the game so much.
Now, Midna was not revealed in TP's first announcement trailer, but she was by the next trailer, and featured in the first Wii demo—I don't recall if she appeared in the first GCN demos or not. Hopefully the SS demo was a foretelling that there would be no helper, though I'm skeptic due to that blue figure appearing in the artwork and supposedly featuring prominently in the story, but maybe, just maybe, that won't mean she'll be a helper, just part of the story. Now, as long as she doesn't physically show up during gameplay, doesn't have an annoying voice, and you can ignore all but her most important messages, I'll give her some slack, but that's only if she was a helper; if she isn't, then we're all good and this rant was for nothing.

But yeah, I want the system WW had as far as helpers go: The little Pirate's Charm was what Tetra and the King used to communicate with you, and you could mostly ignore those if you wished. Of course, I'd rather have no helper at all, but, well, what are the chances of
that happening.
