Metroid prime 3 used motion controls very lightly, and for things which could have been easily replaced with buttons, not that it wasn't enjoyable. As for zelda, they only decided to use WM+ after people screamed in their ears that it would be a good idea. And besides, you don't really need motion for what it's worth in Skyward sword, since looking at the GDC trailer, it's mostly used for puzzles and incredibly rudimentary combat.
And unfortunately, even with 3rd parties, good motion games are few and far between.
Which just shows that for 3rd parties and Nintendo, completely ditching good motion controls doesn't seem to be a big deal at all, since it only represented a very small portion of their portfollio of games.
What Nintendo did with wm+ and Zelda was what in Spain we call "lanzar un globo sonda" and it's something politicians use to do (and please forgive me for this comparison): when they have an idea but don't know how well received it will be among yhe people, they just say that they are studying it and way for reactions. Nintendo announced that they were studying the use of wm+ and people claimed how good it'd be, reinforcing their original plan (if people's reaction were against it they could go back to simple wiimote).
As for the lack of good 3rd party games with motion controls it's only the result of the lack of support from them. No games in general means no games with motion controls in particular, and even less with a good implementation of them.
In the end, Nintendo has said that they want to improve and expand the way we play games, and you don't do that introducing motion controls with one console just to take them away with the next one. Also they have launched the 3DS with motion controls, why would they ditch them in Cafe?
