Episode 13 of Blizzcast, Blizzard's occassional podcast, came out yesterday. The majority of it is devoted to a StarCraft II beta special, which is beyond the scope of this site, but they did do a WoW Q&A after that (and a Diablo 3 Q&A at the end), between WoW CM Zarhym and Diablo CM Bashiok. The WoW segment was mostly retrospective, discussing what the developers learned from Wrath, with a dash of looking forward to Cataclysm.

Here's a quick summary (you can read the whole transcript, or listen to the podcast, at Blizzard's site):
  • ICC is designed such that the final boss in each section is harder than the rest of the section (Putricide, Blood Queen Lana'thel, Sindragosa, and the Lich King).
  • The ICC zone-wide buff "won't come in until at least a month after the Lich King has been released," which means we could see it soon, since the Lich King fight opened up February 2nd (although the devs mentioned in the Twitter chat that it's not quite time for the buff yet). It will improve "roughly once a month," and the buff will affect health, damage, and healing (much like the Luck of the Draw buff from random dungeon groups).
  • They thought the Illidan encounter in Black Temple, back in BC, was a bit anti-climactic, so they wanted to make sure the end of the Lich King was "super special."
  • In answer to "what next after I clear ICC:" ICC hard modes, and to a lesser extent the Ruby Sanctum, which is coming in a future patch. Ruby Sanctum will hold "roughly Lich King level gear," as has been mentioned elsewhere.
That's about it for the WoW content, but if you're interested in SC2 or D3, you may well want to read or listen to the whole thing.
