Nintendo may have published Goldeneye, but that doesn't mean they own it. Just like Capcom doesn't own WayForward's Shantae. Honestly, I don't know who owns Goldeneye. From reading Rare's website, Nintendo, Universal Studios and EA would all have to give the go-ahead on a remake of the game, but that doesn't mean Rare wouldn't have to be consulted too. Nintendo is STILL consulting Rare on the DKC games, I'd be surprised if Rare isn't still in control of the code behind Goldeneye.
Mario: I googled Merrick and Goldeneye and found some hints that they might put Goldeneye on the system, but nothing concrete. Did he ever say anything more than the system is perfect for a game like Goldeneye?
As for Perfect Dark, I like the idea of the game acting as an "ad" for Xbox 360, but I still think it would probably benefit Nintendo way more than Microsoft. There's a very good chance that PD0 will not be as good as Perfect Dark, in which case Microsoft probably doesn't want people having a cheap, superior alternative on a system with better controls. If PD0 can live up to the original in spite of the fact that some key team members left Rare and the game's been in development forever, then a promotion with the Revolution might be a good idea. I think a more likely outcome would be for MS to rerelease the game on Xbox360 through Arcade Live - or maybe even on both consoles! That would be sweet!
