Tricky as 'Released' is not a word that's entirely sure of its tense as it can be past (the original was released 30 years ago) present (I'm being released without charge ) and future (i cant wait until ED is released)
Strictly speaking "released" is past tense in all three of those examples. The first in simple form, and the second and third in passive form (and thus you're describing when it will have been released using non-past verb "being", and non-past verb "is" implies past passive phrase "has been", which is in the future according to the preposition "until").
So, strictly speaking again, it should say either "Elite Dangerous is released in...", "Elite Dangerous will be released in...", or "Elite Dangerous releases in...", or "Elite Dangerous not released for...".
But hell if I care, I'm more interested in the number.
