Thanks to our friends at MMO Champion, the stats for the first two sets of Tier 10 (item level 251 and item level 264) have been released. This looks to be the 10man and 25man (non hardmode) sets. The 25man hardmode set will be item level 277.
I have yet to compare the sets to the other classes, however it does look fairly well itemized. As Balourd commented earlier, only two pieces have hit, and there is no spirit, allowing for both haste AND crit to be on the other 3 pieces. Both hit pieces (gloves and legs) also have a decent amount of crit on them as well.
