A community manager Caydiem from Blizzard has let a small hint leak out of one of his recent lists of what we should be expecting in upcoming events. One of them is, a very touchy subject (Hardcore vs. Casual), where in, Blizzard will be releasing new teir 1 epic armour in 5 man instances in time for the next patch, the artitcle can be found here. Personally, I feel this is FANTASTIC news for casual and hardcore gamers alike, especially for those with work or school constraints, but have level 60 toons!

Patch 1.2: Maraudon (5-man 41-50 dungeon)
Patch 1.3: Dire Maul (5-man 53-60 dungeon with three wings)
Patch 1.4: Honor System
Patch 1.5: Battlegrounds, new mid-level content
Patch 1.6: Blackwing Lair (first raid content patch since launch)
Patch 1.7: Zul'Gurub (raid content, but not nearly as "hardcore" as Blackwing Lair; targetted as a challenge for the more casual 60 and as a stepping stone from UBRS to MC)
Patch 1.8: Silithus revamp
Patch 1.9: Ahn'Qiraj (20 and 40, with some small group content available in the outer world once the gates are open)
Patch 1.10: New armor sets between the Dungeon sets (Valor, etc.) and Tier 1 for smaller group players to pursue.
