HAAAAAAAAAAAAHAHAHAHA, the mage looks even more ridiculous than I feared... for once locks don't look too too mean (they still look kinda cool, but blue just isn't lock-ish). I feel sorry for druids who are gonna look like village people with their little tight pants once again... and I envy the priests who, once again, have a very good looking set.
Hunters, warrs, and rogues look cool too imo. I think all pallies have learned to expect the worse looks from Blizz, well here it is! (shamans look ridiculous too)
That's it for my view on the subject.

I will not complain if warlocks could look like strippers since all other classes have gone through that (exept rogues, they've looked bad, but never gay...)
I'm gonna set up a /dance4mebitch maccro for when I meet one :-D

This looks very much like what the Illidari Council wears: http://www.wowwiki.com/Illidari_Council
So I wouldn't hold my breath over this 

Damn, with all due respect for your work getting these pics Motto, i really don't hope that its the right ones.

They haven't recoloured the glow of the pally shoulders and crown, still that ugly yellow.. Man i was so looking forward to this, hoping that after the ridicules season 2 set, they would give us a little boost in morale by at least doing a nice colour on season 3, but my oh my I am disappointed..

Yellow, green, purple, silver... What the fuck where they thinking..

Priest is looking awesome as usual, damn I envy that set..

Hmmm, I don't know why I didnt notice this topic this morning.

Technically, I can't really news about it, because they're not released yet and we had a few new reskins for the Arena season 2.

But I'd say it could be right on a lot of them, Blizzard added tons of different colors for each set very early in the game (actually, all the colors were available for the 2.1 release) and it wouldn't surprise me if one of the color set was used for arena sets.

Or maybe I was just too lazy and didn't check the last patch enough to find them clearly labeled as pvp sets. I'll check. Thanks a lot for the contribution anyway ^^

Yeah, I was rather hoping the red paladin one would become the arena 3 set. And it very well may. It looks much better than that ugly green 

http://www.wowhead.com/?item=17106yep.

here's what ive seen and understood:
there are three skins for tier armors, one for the genuine set, one pve alt-skin, and one pvp alt-skin (arena).
example shamans: cataclysm shoulders, merciless shoulders, and coral barbed shoulders. same model, one genuine skin, one pve alt, one pvp.

from quick browsing screenshots in random places, i can say with some confidence that the shaman, paladin, warlock, warrior and rogue armor pictures are infact the pve skin, and not the arena one. the hunter, druid and priest ones however are definately the arena skin, druids pve skin is green-themed, hunters pve skin is alot lighter and so is the priests. i'm not sure about the mages one but armor sets tend to be darker than the original ones.
