I don't think it will be scenario only. The vortex is going to fall, and this is going to be cataclysmic and really affect the end times narrative, and the game mechanics. I'm not trying to be Chicken Little screming the sky is falling, and I don't think that these rules will remain when 9th drops. But I do think that, like the legions and the 50% lords, GW intends these to be the rules of the times for now. Obviously GTs won't allow this crap in either. However, it does give me some concern over their ability to write a ballanced 9th edition though. 8th is pretty much as good as it's ever been for WHFB, I am really hoping they don't screw the pooch with 9th.
