Even BMW, Volkswagen and Audi is going away/has gone away from manuals. It's what the buyers want, sadly. I understand it on the C8 since they spent all the money on developing a new DCT transaxle. It's a good unit as well.
It's one of the reasons I got my 1LE when I did, because it was on the way out, my last chance to get a V8+manual. It's also why I snagged the CT4 V BW, get something great with a manual while it's available.
Wish I could get a truck with a manual transmission.
