Apple Insider claims to have gotten their hands on a three page memo from Apple to Apple Store staff containing a form of Frequently Asked Questions. We say "a form" because the officially dictated answers to almost all customer questions are pretty much variations on "we dunno."
Apple also reminds staff that loose lips sink ships. (They're not to speculate beyond the meager amount of information already released to the public.)
Should be easy, given that it's only a few weeks before release, and we still know so very little...
