http://www.ecocitycraft.com/forum/viewtopic.php?f=6&t=2259 As is said in this thread, it's not Andrews choice when we update, it's the developers, and the developers won't be working on the stuff until minecraft is done updating through the 1.7 stuff...Notch has already said that that won't be until at LEAST tomorrow...be patient, it will happen in eventually.
And we will update to 1.7.x not even Notch knows what the x will be xD edit: Looking at it again, I'm not sure if yu're asking if we are updating to 1.7 or if you were asking which one we will update to xD, the most recent one will be it, if Notch stops at 1.7.2, we will update to 1.7.2
