I'll admit I have some doom and gloom myself. I wanted Chi Blast on Monk (along with several other changes) and there was no mention of a ranged attack at all.
Every player has their own expectations about which way the game direction should be going, and it's quite easy to feel let down when things don't go your way.
It should be a blessing that we get sneak previews like this. It's not a good thing for some people though. I think some people would be better off not hearing about any of the changes in advance at all.
"Try it before you knock it" is a fair argument. We do have to wait and see. It's less than a month away, but that is going to be a month of hell for some people eagerly awaiting this!
