Yes, it's there. It's cool. (Insert crickets here)
While demoing the new build of Metroid Prime at the Gamer’s Summit, NOA’s Chris Campbell revealed that the GameCube and GameBoy Advance versions of Metroid will interact in some form. Unfortunately, in typical Nintendo fashion, all he could say is that it would be ‘cool’. Let the speculation begin! Hopefully we’ll have more ‘cool’ news about how the 2 Metroid games interact sometime before the games launch simultaneously this November 18th.
