Fun detail; Deus Ex has ONLY nighttime, it's never daylight in it, ever.
Thats not true: You see the sunrise while leaving vandenberg;)
Back to topic: larian makes their points clear during the development. Regarding to the length of the last two release-notes it was the right decision, to cut the "real" dan/night cycle. Hopefully the game is successfully enough (one week Steam #1 sale) to giv'em enough space/time to reevaluate some decisions made in the past
