GBA to GC connectivity (1 Viewer)

Spaceworld is over. They showed a couple of games with GBA to GC connectivity but not the killer app we were hoping for. I guess we're going to have to play with the lights on with these games. I hope developers have some more ideas up their sleeves that they're keeping secret. Kirby was neat but I want a real must have game. What would really be nice is if each game worked on its own as a game but became something more connected.
Do you think the connector will provide power to the GBA? Then you could use a Worm Light without killing the batteries.

There are some lights that have pass through ports so that you can connect to the GCN and have a light. The GBA is worth itself alone, so the GCN thing is just a bonus. I think that we will probably see something like a GBA Camera come out and use that for games in the future, possibly a microphone or something.

I agree that the GBA is fabulous as a stand alone unit. I bought Mario Kart today. And The Wicker Man. But Nintendo is the only company to have a handheld and console and wish that they could be combined into something more.
