I've watched pretty closely to see what sort of loot would be available (yeah, I know, it's beta) from the raids in WotLK, but I don't recall seeing even one axe for dual weilders.
The orc racial bonus was (will still be?) 5% expertise while using axes. It was one compelling reason to use Rising Tide over the badge fist weapons.
Perhaps Blizzard will change the racial to fist weapons instead.
Lol, not sure at what you're trying to get to, but there is evidentally more than one race to the shaman class.. why should blizz change current item ideas to benefit a specific race.. lol.
Besides, the fist weapons look cool!
The reason is that orcs benefit most from axes. Don't get me wrong, I like cool looking gear, but exploiting any advantage you may have (racial, class, faction, etc.) can all be useful for raiding.
