Epic Mob Questions

[Xebarsis]

I've been told that epic quests won't be released until Kunark is available for about 4 months.

1. If this is the case, are mobs that drop epic-specific items going to spawn within that 4 month period? (For example, The Tangrin.)

2. Are mobs that currently exist in classic that begin dropping epic-specific items with the release of Kunark going to be dropping their epic-specific items before epic quests are released? (For example, will Phinigel Autropos start dropping his backbone with the release of Kunark, or is it going to start dropping once the 4 months are up and epic quests are unlocked?)
