Maybe this too is posted elsewhere as well but I searched for it (I'll include that screenshot just to verify) and didn't find anything forum-wide so I figured I'd add it because it is interesting and I've been following it since it came into the news.
News: 2020 Honda Valkyrie Rune 1800 October 2019
Which was in succession to this announcement:
New 2019 Honda Valkyrie Touring 6-cylinder 1833cc December 2018
A bit of researching, mainly digging for Tokyo Motor Exhibits that reveal the most accurate details and discussions:
2019-2020 Honda Valkyrie 1800 Google Digs
Past that I keep in contact with my local Honda Powersports manager, I like to drop by and we talk bikes and such, who is also keeping up with this new Valkyrie (Rune) as well. His take is that it's still absolutely in the works, has been received very well within the market it's geared towards as well as outside that target market based on the updates/inclusions to this bike, and there has been activity within production already that would coincide with development moving forward. Honda had scrapped a concept prior to this geared towards re-introducing the Valkyrie but that is what apparently led to them going back to look at the Rune and wanting to resurrect those designs into a newer, more sophisticated, higher technology redesign. This is supposed to be the closer incantation of the bike they originally intended the Valkyrie Rune to be and aesthetically I can see the blending there much more on this than on the 05-05 Runes. Honda has been keeping anything to do with this design/production pretty quiet so there hasn't been a lot lately, but if someone here has anything to add then by all means...
