One of my local shops is not participating this year. They found the 'Sew Musical' theme to be too challenging to create an original design. I have to admit that I am not too sure about the theme this year either.
I would stop in the shops, let them know in person that you are disappointed, but perhaps there will be something else in the store that will catch your eye.
I would also write to the Row by Row organizers and let them know you are sad that shops that have participated in the past are not this year.
