I generally like it. I think it will help control the chaos of the show a little. I understand that APs who want to come for the night will miss out but there are people who go on vacation JUST to go to Disneyland and it will give them the opportunity to see it if educated properly.
I know that I would be frustrated/disappointed if I came for a 3 day vacation and had to spend one whole day camped out for the world of color show. I don't know many people who travelled there for vacation that wouldn't be upset by wasting a day. Its like paying for a day just to see one show.
I trust Disney will figure their stuff out. I am also willing to give it the summer and then go some obscure day next fall to see it.
