Adventure packs and Expansion Releases.

When will The Bloodline Chronicles and The Splitpaw Saga Adventure Packs open? When does Desert of Flames release? Will it be 6 weeks from yesterday for The Bloodline Chronicles Adventure Packs to release and then another 6 weeks for The Splitpaw Saga Adventure Packs to open? iI that is the case will The Splitpaw Saga Adventure Packs and Desert of Flames Expansion release at the same time? will it be a full 24 weeks before Desert of Flames releases?

Going by what the FAQ says it's 12 weeks between expansions and adventure packs 6 weeks after the expansion which would make it 12 weeks to Desert of Flames and 6 weeks till both Bloodline and Splitpaw.
On the other hand this seems to be the only time there are 2 adventure packs in an expansion (well, the original release actually) so they might vary it a bit. It would make sense, given the original release schedule, to have Bloodline after 6 weeks, Splitpaw 3 weeks later and DoF 3 weeks after that.
But the FAQ says adventure packs 6 weeks into the 12 weeks until the expansion.

So it sounds like they will release both Adventure Packs at the same time or delay the second one a bit. By chance when did the Epic Weapon quest become available to start?

Original epics came out with Rise of Kunark, so four expansions in.

Any good armor quest lines in the original game? Are Gildas' Requests, Ian's Forgetful Family or Selwyn's Errands quest lines in?

Yes, and they all have updated stats. Not much blue stats, but really solid for tanks.
