There were few new Nintendo games at GC, but lets face it nothing new here. Here are the games that did make to GC:
Wii
New Super Mario Bros.
Wii Fit Plus
Wii Sports Resort
DS / DSi
The Legend of Zelda: Spirit Tracks
Flipnote Studio
Rhythm Paradise
Professor Layton
Style Boutique
Mario & Luigi: Bowser’s Inside Story
The few games on Wii I was not that interested in but DS has few I would like to buy when I get the chance.
Title/ Size
Bird & Beans: 11 blocks
Master of Illusion Express: Funny Face: 19 blocks
Art Style: AQUIA: 91 blocks
WarioWare: Snapped!: 61 blocks
Brain Age Express: Math: 71 blocks
Nintendo DSi Browser: 96 blocks

The question most people aren’t answering is just how much DSiWare can you put on the Nintendo DSi.
Nintendo has an early list of DSiWare file sizes.
The sizes are measured in Blocks. Now the Nintendo DSi has a internal memory of 256 MB which is 1024 blocks. No this does not mean you get 1024 DSiWare.
Opera browser one of the larger DSiWare is 96 blocks which means that the internal memory can hold around 10.5 Opera browser. The file size will vary so there will not be a definate file as far as I can see. The Price range on launch will be 200 -800 but the like the opera brower it can be free and some will go higher the 800.
So try and remember that when downloading.
