Considering Rockstar probably got the most useful thing out of them (the face-camera tech), and Team Bondi was horribly managed, I can't see Rockstar being anything but happy dumping what is by now a toxic asset.
Edit: I played a bunch of these games. But as many people have pointed out, it's hard to make a golden age when games age so poorly. I'm sure a lot of people would like to point out all the great games that came out before the 90's and tell you you're wrong.
Nintendo could make a profit from these if they did an Atlus and released a limited run. Or you know, Atlus could pick these up. Or hell, Ignition. In any case, I think Nintendo gave fans the finger because it doesn't want its hand tied. It'd be foolish to assume Nintendo isn't at least looking into releasing these games right now. If they think they can make money, they'll do it. Or they can just ride it out until the WiiU. Or release a triple pack called "The Nintendo Leave Us the Hell Alone Now" pack.
