From TMP:
20th Century Fox announced today the launch of their DIGITAL HD service which will bring streaming HD content from their catalogue through a wide variety of devices. The new service will bring more affordable prices (hopefully) and even early launches of films. Take Prometheus for example. It's availble to stream today, about three weeks ahead of its blu-ray release.
and im unsure if the vita "which i havent gotten around to getting" can even handle the format or not
I've done it twice and both times it was a giant pain in the ass. You had DRM blocks along every step, and it wouldn't transfer to ANYTHING. I had a Zune, phone, and PSP and only one movie would go to the PSP, thats it, and it had to do it in some particular way.
