According to N4G, Banjo-Kazooie's second N64 outing is heading to XBL along with the original.
They may - MAY- be looking to bring the original Banjo-Tooie - the one teased at the end of BK1, with the secret areas and swappable cartridges (though, obviously, without the cartridges). If this is true, it is wonderful news for fans of the franchise. I've waited almost as long for this as I did for the first Star Wars prequel and an Alien vs Predator movie.
On second thought, those probably weren't the best examples to use.
