I was just about to post about the price increase and noticed Penguin beat me too it.
As for KSP releasing over the weekend/this week the chances are slim to none.
They've pretty much stated that the game wont be releasing before KerbalKon on Friday, and after .16 they've stated that they wont be releasing any more updates on Friday's or weekends.
As for the reason for no releases on weekends, If I recall correctly the servers died during release and everyone was enjoying their weekend, so it was pandemonium.
