Well, I can say that I, who has had some modicum of tolerance for all the antics of Season 37, am skeptical about this. One interesting thing that was brought up in Roger's Shokus interview was how the Groucho Marx glasses on the April 1, 2009 show, the host put it, "covered up people's faces, so we couldn't see who they really were." Wearing costumes is taking it to the next level.
Also, the lines of decency may be crossed with this one, if they are not careful, but I think they have enough sense to not allow those with rather risque costumes to enter the studio or ask that they try something more appropriate.
I won't comment on it until I see the show, but I do hope that it won't be a trainwreck.
Oh, it stinks that our friend, the Italian Chef will not be in this one as well...
