I recently saw Ghostbusters 2 on E4 (I think it was on TV like twice within a weke or two). I have mixed feeling about a GB3.
If they get the old cast back together they will be too old.
It might get the ol' Hollywood white wash of special effects (dont get me wrong it would be nice to see a Ghostbusters film with better visuals but i think they might go OTT).
I don't want to see a remake with new actors - it just wouldnt be right.
So far the best idea is to have the original cast perhaps, training some new people. But again, I don't think they would get this right...
...Just imagine it now they teach these new kiRAB everythign they know. The kiRAB will probably start off all cocky, then the orignal GBs will prolly get taken away somewhere (like Hell perhaps?) and the new kiRAB will al be like yeh lets save them and try to look uber cool while doing it.
It would just be awfully hard to get the story and cast right for that storyline.
Personally, I think there best betwould be to do a completely new film with a different cast. And not have it relate to the first 2 GB films at all. A bit like they did with Batman Begins (which I thought was gonna be awful), they jsut ignored the first 4 films and never enve tried to make reference to them it was a new film, new story, etc. Though I'm not suggesting that the GB film be a prequel of sorts at all.
