Hey you need 17% hit when 4.0 hits

[Trivial]

I know that blue gems will be the hit gems in the future, but is it known for sure that a ametrine with 12 sp/10 hit will actuelly turn into a blue int/hit gem? It sounds kinda wierd, because then they would also have to change the sockets on gear and stuff for people that had gemmed orange to get a set bonus.

Would pre crafted gems not yet equipped also change?

Lastly is there a webpage with an overwiev of the gem changes?

I transfered my shaman and my DK over to PTR, and both lost their socket bonus where there was a Velied/Etched Ametrine because it turned into a Dreadstone.

So, yes, you're gonna be losing socket bonus.
