16 pre-generated character sheets hidden on WotC's site

I was attempting to find the missing PDF for Monster Slayers: Champions of the Elements.

You have seen the original Monster Slayers pdf, correct?

If not, it is free at dndclassics.com: http://www.dndclassics.com/product/123538/Monster-Slayers-The-Heroes-of-Hesiod

They look to me like the quick sheets used in playtesting DND Next before release as 5E

Yep, these are characters that are pre-approved as pre-gens for Adventurers League play.

What's interesting to me is that these are billed as being based on Sword Coast Legends NPCs; bit, they use pictures from the PHB. Does this mean that a lot of the example characters in the PHB were actually based on the NPCs the devs knew were coming?
