Don't worry about speculation, especially when it includes Zelda, because Miyamoto said that they weren't. They might be working on something new, but they are certainly making DKCR2/U. DKCR sold more than Prime/Echoes/Corruption combined, so don't expect a Metroid from them for some time.

Ridley has the best chance, presuming that Sakurai can get him to work. The resizing arguments regarding him that I've been hearing from some people are unrealistic, and don't at all expect that. Dark Samus has a shot, and I think Fusion Suit Samus may as well, given that she is the future of the series. Her best chance would be if Sakurai has inside knowledge about a game that finally advances the timeline.
