When I was there in august of 2010 I want to say that wishes was replaced for a few months but another show....It was a good show and it was nice to see something new but the next year we went back wishes was back and it was a nice thing to see. I am 50/50 about it...as much as I like wishes I am ready for a change!
Yes that was part of the Summer Nightastic that also brought back the MSEP.
