As promised, here are the screenshots I took last night from the PTR. This looks like two full sets of item level 358 PVP gear purchased from the trainer and the cloth vendor (11 trainer/6 vendor). The Embersilk set appears to be slightly more healer-focused with two of the pieces sporting Spirit. The Fireweave set is probably intended for damage casters, although the distinction is pretty small with these items.
Here are the recipe images from the Embersilk set:
Of these recipes the Robe, Pants and Cowl are bought from the cloth trader. The other six recipes are available from the trainer. These recipes exactly mirror the current Emberfire items, so this appears to be the same upgrade situation that I found with Leatherworking. The component materials are identical to the existing recipes.
Here are the items in the Fireweave set:
The Pants, Robe and Cowl recipes are bought from the vendor and the rest are learned from the trainer. This set does not include the new Cape recipe as the Embersilk set does. The cape is the only new item in this list, prior to this Tailors had no crafted cloak for Cataclysm. Personally I think they could use a couple more for PVE healers and casters, but that's just me :)
Be sure and post in the Comments if you have any questions about these items or want to suggest more research for a future post!
