I've made no secret of my advocacy of this project. However, the "... if it was still 1998" comment does ring a little bit true to me.
But for all that, I still would have loved to have seen this come to fruition, but there are always going to be two camps on this. The one lot who are willing to overlook the magic facehugger and hand-waving (or brave dramatic decision whichever way you want it) of two established characters and the other lot who can accept A3 on its own merits... but not at the expense of the established story.
We've been over it loads (the joy of the internet forum) and I don't think anyone will really change their stance on this.
The one worry, I think, is that even if it had gone into production, the question marks over NB's ability to deliver on the concept would still be there - would this have been the movie that the Aliens fans wanted? Was the script - and the director - up to the task.
It's a moot point now - as has been noted, he's moved on. He knows its not happening and this Oaks studio thing is the new thing d'jour. Fair play, a lot of the content seems to be saying "And here's what you could have won" re the AlienVerse!
