I suggest going to a major quilter's conference, AKA a quilt show. There you would see what quilters are interested in. All the research has already been done for you. Also, hire a person who quilts, I mean REALLY QUILTS, to be in charge of finding the drops that will make the quilting community SPEND, SPEND, SPEND. I am that person who stands out among my quilting community who has every gadget, every ruler and and enough fabric to open my own quilt shop. Quilters are like NASCAR fans. We are dedicated, passionate and ever so serious. We will pay big bucks too just to feed our quilter's soul.
