Don't get the bitterness. They said very early on that linux will be aviable at release (-> not before). If they break that promise, i will be bitter. But being bitter about something they never promised seems strange to me. Adding a "and Linux will be aviable at release"-line to the update seems redundant.
Just have patience for one more month - or start a Virtual Machine with Win/Mac. Also, if you are a linux guy you'll probably know this: "no news is good news"
