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.
