I don't know why everyone is getting all worked up over a potential manual offering. This reminds of of the 2021 MY changes all over again.
Just my 2 cent:
1. Be happy with what you have.
2. The more to pick from the better.
3. Changes and improvements are going to happen.
4. If you don't...
Maybe Toyota is introducing a new trim level for the manual?
Down in Australia the 3.0 comes with the 18 inch wheels and unpainted brakes.
