We all know Miyamoto has confirmed many times there will be another Wii Zelda. Also, I know that most of the time, the games aren't direct sequels (usually a different Link in a different timeline).
However, there are many plot points in TP that people wanted addressed, and it didn't really seem like that games' story was over. Dark Link is seenin a flashback but never battled in-game (not the Ocarina Dark Link), it's not COMPLETELY clear what happens to Ganondorf in the end (to me, anyway), and it really seemed like we were just scratching the surface of Midna's story. Midna was also just starting to get awesome near the end. You don't know much about Ilia, either, and there are many other characters that are highly underutilized (abominable snowman, anyone??). Not to mention the fact that the final scene makes it look like there may be a true relationship developing between Zelda and Link in the last game (as opposed to the friendship they usually have).
So, that being said, will the next Wii Zelda star the same Link from Twilight Princess, continuing the story a few years down the road?
