Famitsu recently interviewed Testu Kayama of SEGA, and it has now been translated for your reading pleasure! Although a lot of the interview is about SEGA, stuff about Nintendo creeps in. Below is a quote from Mr. Kayama. Check the full thing here. And don't forget to check the page tomorrow for the second half of the interview!

"This time, as we will supply software to other console manufacturers for the first time, I would like to complete the preparation of all the different development environments for our creators. In fact, we had already settled negotiations with all of the other hardware makers by last November. Because of that, now we already have development tools for PlayStation 2, Game Boy Advance, Nintendo's Gamecube, and Xbox, up and ready to go."
