I remember when all the Wotlk info was leaked we saw new armor sets witch we assumed to be tier 7 , and they actually turned out to be tier 8, they just recycled tier 3 into tier 7.
Think its possible they may pull the same thing on us? show us all this cool gear and it not even be what we think it is ? I know the main reason for the recycled tier 3 was because of Naxx but it still might be cool to see what some re-glorified versions of older gear would look like .
