I agree with you habu987. Also, the hybrid and PHEV version does not get a second-row bench (3 person) seat, just the 2 seat captain chairs.
I assume since this is the first-generation TX, maybe on the second year production or even later the second-generation TX would have the option for wood trim, more choice with interior options and exterior colors, etc., leather options, wood trimmed steering wheel option, massaging seats, acoustic glass, triple beam headlights, etc. I want to put down a deposit for the TX 550h+ but as you mentioned the TX is missing many options, choices, etc...
I doubt there would be second generation TX unless something goes wrong with Lexus being all BEV brand
