... that after stating the six levels of rarity in the playtest packet, the next paragraph was NOT:

"Magic items are uncovered in packs of six. Each pack contains three random common magic items, two uncommons, and one item of either rare, legendary, or artifact status. In every 100 packs, 60 will contain a rare item, 30 a legendary, and 10 an artifact. You may trade items with your fellow adventurers and try to build a compete set. Also, special foil embossed artifacts will be given away to the winners of sanctioned dungeon crawls. Check with your local magic item shop to learn more about officially sanctioned crawls."

I mean, come on. This is Wizards of the Coast we're talking about. I think they showed remarkable self-restraint by not putting that in there.
