URF

So is Riot playing a prank by not releasing any info on URF or is it just me? I know they are doing a stupid rotation thing with different game modes every so often but I've been looking forward to URF for a damn year. If I only get 2 days to play URF, so help me God. I have to work Saturday and Sunday and if those are the days it is available, I'm going to be livid. Someone please fill me in about this. I wanna know what the hell is going on.
