I wish I could eject the disc using the remote. I would like to press the power button quickly to eject the disc, but still allow holding down the power button to shut the unit off without ejecting the disc.
If a GameCube disc is in the drive, when I switch the unit on I should be able to press (A) on the GCN controller at the warning screen to immediately launch the title. It is highly annoying to have to fiddle with the Wiimote and menus, then swap to the GCN controller just to get the game launched.
I want to use the USB ports for external storage devices.
I want a stronger strap for the remote. My seven year old busted the strap while playing tennis, luckily it hit the wall and not the TV. There was no damage done to the wall or the Wiimote, so it wasn't a massive strain on the strap.
I want GBA games for the Virtual Console. Two of my favorite games are Metroid: Zero Mission, and Metroid Fusion. I own both on the GBA, but these games are so much more fun when played full screen using a full sized controller... thank god for VisualBoyAdvance and the SuperJoyBox 13!
What would you like to see?
