Prometheus or Covenant?
I doubt it. Not for some time anyway.
Their original 4K release
is far too recent.
As for Alien, Aliens, Alien³ & AR.
It's difficult to say, Director
James Cameron seems to
have no time for home media
releases anymore. (Aliens)
Addendum: Be careful
what you wish for.
(Judgment Day 3D/4K)
And we all know how
David Fincher regards Alien³
-unless something's
changed between
1992 and 2018.
I'm willing to entertain the idea,
the possiblity that Alien will be
the only one of the original four
on 4K, for some period of time.
Unless Charles De Lauzirika
oversees all the Alien sequels.
Jean-Pierre Jeunet's
likely to return though
I'd say, with a big bowl
filled with DNR.
Although he said the
transfer for Resurrection
didn't look as "Silver"
as he'd intended so
I'd be interested to
see that if possible.
