I think 3 years ago there was a new cruiser or two. They were both a little more than two years in the making. They were also a surprise to most. So the idea of "spy photos" is the only argument you have. Triumph is apparently very good at keeping new models hidden from the fact finders.
No matter what you believe, it doesn't change the truth.
A new cruiser (to fill a void) is in the mill. The Rocket III is a cruiser. Where have you been? Go back to your Harley boutique and dream away. That's what you want anyway.
