I notice the OP doesn't mention any Nintendo made software in his list of titles he looks forward too. This makes me wonder if you don't really like Nintendo's first party content. Selling your Wii in 2008 makes this even more obvious. If you don't like Nintendo's first party content, the answer is simple. Do not buy a Wii.
Wii like most Nintendo consoles lacks third party support. So if you don't love Nintendo's own titles this is not the console for you. Then again Monster Hunter Tri and Red Steel 2 are both looking like amazing third party support. Other notable titles to look forward too are Pikmin3, LOZ, Mario Galaxy 2, Metroid The Other M and Vitality sensor!
