I'm not the biggest fan of the schedules - but I'm not opposed to them either.
While I really enjoy a day/night cycle, I'm also conflicted over NPC schedules. I like them right up until I have to wait for someone to wake up in order to move a quest forward.

I'd be perfectly content if they added them in a later patch. However, it seems like something that would need a lot of QA, and if it comes later they will lose the opportunity to take advantage of this alpha/beta testing. Tough one.
