2016's will "introduced" via a purposefully vague internet video with vrooom vrooom exhaust sounds, a voice over by a seriouly strident semi constipated sounding announcer who will tout some poll tested wording that the HD marketing department yadda yadda'd over for at least a month, & the pics online will not be as good as looking at a bike in person.
The Unicorn/Rainbow/Flying Monkeys from the Wizard of Oz paint schemes have been placed on hold until 2017. Pool boy sourced, so it must be true.

No Wizard of Oz paint schemes? I'm wounded.
For the touring line they need to get that infotainment system up to snuff. BT Headset protocol and a number of bug fixes.
The Dynas are great. They're old because that's the market for that kind of bike. Go fast, stay cheap (relatively speaking) and make it practical. The sportster line is in the same shape.
The Softails appeal to a market that Harley abandoned before they ever really went after it. The young rider who survived the sportbike years and now wants to look cool without hurting him or herself. No brand loyalty in that market because Harley never really pushed Buell to compete in that market. You can't save a product people don't want.
The V-Rod. They have to kill this off soon. It's the best designed HD and they've completely screwed the pooch with its placement and further designs to go with the motor. The streets aren't a bad idea, but I don't see them saving the revolution.
Sooner or alter people are going to realize that a CVO is no longer special. No longer hand made, it's just another model rollin down the assembly line. No longer higher end with the electronics. No longer a significant motor upgrade to "factory". And the paint schemes... well, how custom is one of 3500? Buy the bike and take it to a paint shop.
So will they address any of this in 2016? Will the Wizards Monkey's fly out of my... well. I'm not betting and I'm not buying. Year 8 on old Screaming Nemo. I took the new bike out of the budget after the Rushmore bikes proved to be less than advanced electronically and less than reliable although they do seem to be back to their pre Rushmore reliability...
So my CVO guess is a Softail. Move the wet head into that line to test the waters (pun intended). The others will be touring: A Road Glide. A Limited. A street glide. No engine difference. Updated Paint. Same stuff different year.
