I thought they were thinking of bringing those to the Virtual Console.
You know... even though Rare is owned by Microsoft... I believe they still brought you a couple Game Boy Advance Games (or maybe it was DS... I cannot remember the title(s) ).
Yes, because the GBA/DS is the handheld front, something they can legally do since the 360 has no handheld. The Wii and 360 are competing sort of, so Rare can make nothing for it.
