Apparently one of the posters here was actually seeing / hearing an actual 2020 LEAF near Smyrna charging here: https://mynissanleaf.com/viewtopic.php? ... na#p573981
The article referenced above by Orient does say that a new sound called "canto" would be used as the pedestrian warning sound. The Smyrna poster reported hearing a "tron" like sound which matches the sound originally revealed here: https://youtu.be/p4cjPk8mqEM
The Smyrna person also reported a "large" screen so that seems to match the article stating upping the size to a 9", which is 1 inch bigger than the 8" unit on all plus units. It likely also has the full LCD instrument display with no physical Speedo.
Would be interesting to see what other features make it to production in the USA. Given that the debut isn't until 2020 Feb in Japan, it's likely around then we will hear for sure what really be in the NA / Europe versions.
