MMO-Champion has just posted what appears to be the patch notes for the WoTLK Friends and Family Alpha. This is an unconfirmed leak, but everything on them would appear to check out as legitimate. They're pretty barebones, but there's some intriguing information to be found:

* Death Knights are playable, although the starting quests and talents are not complete.
* Spells and Talents past 70 are available for the Druid, Mage, Priest, Shaman, Warlock, and Warrior classes
* You can head to Northrend via Menethil Harbor and Theramore for the Alliance, or Undercity and Ogrimmar for the Horde
* The Howling Fjord, Borean Tundra, Grizzly Hills, and Dragonblight are the zones currently open for testing.
* Utgarde Keep, Utgarde Pinnacle, The Nexus, and Drak'tharon Keep are currently available for testing.

If they already have talents for quite a few classes past 70, it would seem to suggest that they are further along on the expansion then we think. Hopefully, if these patch notes ring true, we'll hear about those talents soon. You can read the full Patch notes behind the jump.
