Harley has always taken the approach of taking existing tired models and doing minor styling stuff to create "a new model". Willy G used that approach to death, even going so far as to change the paint and call that a "new model".
If Harley plans to release 100 new models over the next ten years, I'm sure they are counting all those small bikes they plan to build and sell in India and China. To get to 100, I'd assume they are continuing the Willy G method and will call every tiny cosmetic variation a separate model. When corporate suits spew this stuff, it's directed more at investors who know nothing about the actual products versus real consumers of their products.
In the US, they desperately need to replace the Dyna and Softail models with new from the ground up products. Changing the bars, installing wider tires, and changing paint and graphics doesn't cut it anymore. They also need to decide what to do with the V-Rod platform. Either support it with design changes or kill it off.
