Hm. So it doesn't sound like any of you are really happy with the Wii. That's a shame. For me, Nintendo is still delivering the goods on their first party software - you remarked that they were conservative with their new games, and I would only say that applies to the base structure of these games, as I feel like there was a lot of imagination and creativity in most other elements of their game design. I also disagree with Mike's characterisation of Metroid Prime 3, but whatever floats your boat. As for third party support, it might not be as strong as the other systems, but I think there are still some diamond titles out there. More than ever, though, you have to be very much tuned in and looking closely to find those diamonds.
To bring up a few that I don't recall being mentioned on the episode, both Zack & Wiki and the Boom Blox duo definitely delivered on what you were discussing, the promise of new experiences brought about by the Wii controller. Original, clever and great fun. If we extend this to the download arena, I'd put LostWinds and Fluidity/Hydroventure under the same category; these are the kind of games that you couldn't get elsewhere, the kind that are made more enjoyable by motion controls. Of course, that philosophy isn't required for everything; two examples are Little King's Story and A Boy & His Blob. Despite not utilising any special control scheme, this pair is the kind that probably wouldn't be created without the Wii either, simply because of industry trends.
As for disappointments, the conspicuous absence of certain games on Virtual Console is a big one. Supposedly, the lack of representation for Nintendo 64 is related to difficulties emulating Expansion Pak features, yet it must be possible given that there are ROM websites that have managed it.
