There is no info how it works, Just that pure text about few things like race Name, class Name, ui and talents. Its a preview pack, no Press pack yet available.
As for a race, Yes it have a tail. Wings model is similiar to netherdrakes with a bit transparency. Also dragon form dont look on screens as it have weapon model showed, there is "Just" a dragon form which look like channeling something. "human" form wearing armor similiar to mail armor.
With talents i can write that it looks like we will have finally posibility to Save talent setup. There is something like around 40 points to left side and maybe 30 or something like that to right one which is probably to spec and left to class but its based on what i remember since last monday. Simply looks like its close to wotlk talent trees mixed up into 2 instead of 3 columns.
