"I hope they will develope new products that will do well in heavy shaded areas, heavy clay areas and heavy sandy areas as well as areas that have a low rainfall amount per year."

Have tried a lot of different stuff in shady areas and nothing worked. For heavy clay, heavy sand and low rain areas try milo, cowpeas and clay peas.

IMO:A lot of the brandsare over blown.I do not like to use Round Up or anything like Round Up. If one disks up a plot well and plants it thick before the spring vegetation gets a hold there will not be a problem with weeds and grass. Our fall plots are not planted until the Johnson grass turns blue or Big Blue Stem grass turns brown.
