The 3.0 patch notes will take a long time to read out anyway. With English translation it will double that length. Its the reason the last live letter went over 3 hours. Its not like we wont be able to read them ourselves.

As for why at E3? Because that's where they will be and Heavensward will be launching pretty much the moment E3 ends. Its not like they have another window to do it in where there would be any point to it at all.

Why are people fixated on this? I thought people would be far more interested in the Live Letter instead where they will actually be showing off new ingame systems.
