If that's true, then I wish he'd stick with whatever his original idea was.
I think it'd make this whole canon argument mute as he'd be able to tell a self contained story that'd fit in the rich lore of the original films and add more with whatever it is he brings to the plate. I'm all about adding more interesting stories to an existing one, giving it an in-universe history to look back on.
In the end, whatever happens, happens. It's his film and he's the one getting paid by Fox should this not get cancelled, he doesn't really owe us anything.
And yet, I still hope he doesn't incorporate Ripley into it. I want him to for once break the cycle and give us interesting new faces to meet.
Oh well, it's still not going to stop me from enjoying Alien 3 and Resurrection and just borrow whatever concept I may like in this new film to add to the old while disregarding the fact it has Ripley in it, I'll just pretend it's Hick's cryotube fuelled dream or something, Blonkamp can mess with the canon all he wants, but he can't mess with the power of head canons.
