Yep I saw a 2020 today and sat in the new rear "captains chairs" with no center console in a Touring trim and I was not a fan. It felt and looked a little naked. As this video shows they are on slender side to side and this guy is not a big guy either. It looked a little unfinished kind of like Mazda said " well we need to do something and others offer this option so lets do that. Other than that option and the bigger screen nothing new. They didn't even update the grill. I'm good with my 2018 for awhile.Here's a video of a 2020 Grand Touring on a dealer lot. Looks like the GT doesn't have that center console between the captain's chairs and is just open. https://www.youtube.com/watch?v=bkB-K1hZtyc
I also noticed that the front center console top is now matched to the leather color. On my 2019 GT with Sand interior, the front center console top is black.
And the new key looks awful. It seems to be about twice as large with no additional features, unless I'm missing something.
