Is there a dominant design style?

[mrnoble]

I wonder if the advances over the last several years in product availability and information sharing have resulted in major changes to the way teams design and build their drive bases and superstructures. Is WCD now dominant? Did vexpro revolutionize the sport with versaframe? Are more teams building swerve drives than ever before, thanks to products like andymark's? I'd love to see what people think of where their own teams are, and where they think things will go.
