Season 4 Information Straight from the Horse's Mouth

Drysc confirms the obvious:
There will be no changes to gear availability/rating requirement until Season 4 starts, which will not begin when patch 2.4 goes live.

When Season 4 starts here's what will happen:
Season 1 removed
Season 2 moved to honor
Season 3 rating requirements and prices lowered
Shoulders: 1950 rating
Weapon: 1800 rating
Season 4 gear added
Season 4 isn't expected to begin any time soon, but as always we plan to give at least a two week notice before it does. Stay tuned to these forums or any of your fine local fansites as I'm sure the information will spread fairly rapidly once we do announce a Season 4 start date.
So basically he said to stay tuned into WoW Vault for more information. Duh! Read the original post here.
