Where's the 'When it's tested and ready' option?
But seriously, what time is it Markus time? ~4:30 pm? I'd imagine if it'd be released today, it'd be in the next few hours. That way he could lurk and make sure everything was going smoothly, then hit the sack. It beats putting it up at 11:30 pm at night, going to bed, and waking up to hoping that everything went smoothly.
I really hope it's today, that way I can play around with it this weekend, and determine whether it consumes enough of my life to postpone buying The Sims 3 for a bit.

(Does that make me less of a man?)
Like so many others though, exams begin for me this Friday, and continue all through next week, so I might have to use my approach which has gotten me through college so far...
Read a chapter, play an inning. Read a chapter, play an inning. etc.
