The original Cuatro promo has been pulled from YouTube.
I found two other versions that are still available (at least at the moment). The first is a version with English text, which I think was fan-made:
The second was narrated by Terry O’Quinn (Locke). The translation here is a bit different from the one widely circulated with the original promo. What before had been translated as “destiny” is here translated as “fate.” I actually liked “destiny” better, because of the way it echoed the language used in LOST.
