I see it differently - they needed to redesign everything except the power train. I.e. in addition to the interior, externally it should have been looking way upscale from 3/Y. Giving that their design language is already almost 2 decades old, they needed (and actually would still need it for 3/Y max 5 years down the road) to have a full redesign for S/X similar to how BMW did with 2002 7-series trickling down that design into 2004 5-series and 2006 3-series (or like Mercedes did with S-class in 1996 and trickling down that to E and C later)
