I don't think anyone has said this, but TSA has started a new thread over at Gamefaqs where he answers all the questions people have about TP. This right here is second hand, as in I got this from a guy talking about the thread, but so far he said the following:
- there will be a Goron themed temple (what a shocker)
- a snow themed temple will also make it's appearance
- the Deku Tree and lord Jabu Jabu will also, most likely, appear (he didn't actually confirm this as much as saying the chances are good for them to be included)
- the map will be more "flexible", meaning that you can reach specific areas without having to go through designated entrances as seen in OoT
- there will be more than one body of water (lakes and so forth)
- there will be new boots for Link to wear
