I am curious about the sleep cycle of the upcoming Nocturnals.

An SL "Day-cycle" is 6 hours I believe, of which one hour is night - the time when our current Meeroos sleep.

Will the Nocturnals be awake ONLY that one hour of night?

And what about the possible hybrids? Will they sleep at all?

I had a room-mate that rarely slept, and while it was great to wake up and find the bathrooms sparkly clean and all the cereal alphabetized, it did make him crazy after a while ;)
