Stop talking about date of release. It will be released when it will be ready. If you want play 3.7 ,get beta and enjoy it :P I know that it has few bugs, but you want it as soon as it is possbile...? Well...get it :P
I stopped talking about 3.7 , because after such delays they are working on it to be god damn detailed (i think so )
So just play tb and be patient :P It will be great
