By this long after the release of Prometheus, I had already seen the movie twice and pre-ordered the collector's edition blu-ray. I haven't seen Covenant once yet and already know not to buy the blu-ray. I bought The Martian twice, Alien, Blade Runner, Gladiator and Black Hawk Down three times, and Kingdom of Heaven four times. This one I'm not even very crazy about seeing, much less buying over and over again when the studio double dips. I'm holding out for the long version with commentary and documentaries. I hope the first release has all that, but I expect Fox to pull a Martian and double dip.
