Cataclysm Questions

soo... i was just wondering if i could get some questions i have about cataclysm answered...

1) how does the worgen work? will u be in human form most of the time? or can u stay in worgen form all the time if u want?

2) Also... does this expansion look really good? cuz WotLK was sort of a mess... and i am hoping this expansion will be awsome and clean that up...

3) is there a release date on this yet? cuz i really wanna play a worgen lol so i hope it isnt too terribly far away...

thanks
