That will not be the case here. Tier 10 purchasing has been streamlined further, and I think this is the best solution as it contains elements of both tier 8 and tier 9 models.
Now when you want to buy tier 10, you have to use Emblems of Frost to purchase the item level 251 variants. This is the lowest version of tier 10 you can get. In order to get the next level which is item level 264, you'll need to get a class specific token which presumably drops from Icecrown Citadel on 25. It could drop from Icecrown Citadel 10 after taking down Arthas or doing some heroic versions of bosses. We have no idea yet.
In other words, if I want to get item 264 versions my shoulders, I have to first spend 60 Emblems of Frost to get the Crimson Acolyte Shoulderpads. Then I have to raid and patiently wait for a Conqueror's Mark of Sanctification to drop (Paladin, Priest, Warlock). Once I get the mark, I visit the tier vendor in Dalaran and turn both of them in exchange for the Sanctified Crimson Acolyte Shoulderpads.
In other news, tier prices also released. Gloves and shoulders can be bought for 60 Emblems of Frost, while the Helm, Legs, and Chest can be had for 95.
