Don't worry, good Nintendo games will come out sooner or later. Now, you have both a Wii and a HD console. You won't miss out on anything this generation, and this is what makes it a very good one in my opinion, especially for "former Nintendo fanboys."
I even got out of my Nintendo fanboyism when I got my 360. Then, the PS3 followed, and I discovered new games from IPs I dared I would never touch before, like Ratchet & Clank: Tools of Destruction. I found out that I missed out on a lot of Sony's 1st party offerings because I was "blinded," if I can put it that way.
It's like if I got out of a bubble and discovered that there was more than what Nintendo offered with Mario, Zelda, Metroid, etc.! I have to say that Nintendo used to offer games like Mega Man, Contra and stuff before... but whatever! The past can't be changed, developers move on, and Nintendo is just adapting to their unexpected success with the casual audience. =P
