The whole "All Lexus sedans to be redesigned by end of 2006" line is hyped up marketing crap. Just like Toyota's marketing that 6 out of 7 of its cars gets 30mpg or better. You can apply that redesign line to a few other premium brands.
These lines hold true:
All Acura sedans and SUV to be redesigned by end of 2006.
All BMW sedans to be redesigned by end of 2006.
