I'm still somewhat amazed they haven't found a better way to handle updating the store. I understand that there is a marketing aspect to taking it offline, but it should be back online and updated immediately after the event is over.
I'm not so sure it's all marketing. Apple is the most inflexible, arcane company imaginable when it comes to web software. They're still using a legacy technology (WebObjects w/ Java) that died many years ago, and everything I've heard about their web team make it sound like their're stuck in technological legacy handcuffs.
It was briefly online after the event, but it was hammered with requests, so they've shut it down again. Maybe they're just throttling the traffic so not anyone can get it, or maybe they took it down completely to do some magic to better handle all the traffic.
I think that's reading a bit too much into it. The product has been announced, having the store down now does nothing to promote it (as having it down during the announcement might), it only prevents people from buying it.
