I think an estimate of $150k for LQ F is a little unrealistic. If the base LQ is priced somewhere around $85k (in between the other flagships, LS, LX and LC), I cannot fathom why an F model would cost nearly double. IMO, base of $85k is even a little high for a car like this... the sweet spot would be something around $75k base because it creates a logical "step up" from upper end RX and GX
no.
If it is going to be LS CUV, then it will start at least 5k over LS. It is not going to be cheaper.
What you will see on the other end is that RX and future GX will likely start getting even higher trims and engines and prices in the future.
Or maybe they make sportier version of RX like Audi did Q8. Or maybe new GX will become that in-between model, properly.
