Some more info from the Op/Flashpoint chat (I'm sure a video is being uploaded right now somewhere)...
- Current Ops are easy and the next "tier" will bring a new level of cooperation (WTFPWNED)
- The new tier of PvE and PvP gear will have stats more applicable to that content type, George specifically said "Battlemaster gear won't be very useful in Operations"
- Georg has started a drinking game, every time someone from Bioware calls an Op/FP a "raid" he's calling out "Drink!"
- Reverse Engineering of Operations gear drops... more details and specifics coming later on.
