Not really as they closed the line as everyone who wanted a new one already had one. Also B757-300s didn't exactly sell well either, it's a pretty niche aeroplane. The bottom line is the B737 proved to be more mission adaptive and longer lived, spanning three generational ranges to the B757s one. Now that's not a criticism, I have happy memories of flying on many BA shuttle services, and of course the high end missions are beyond the B737. However it's nowhere near big enough gap in the market for a bespoke replacement and the B757 design is 33 years old now. 15 is way too young to be mourning the passing of aircraft, try realising that you saw Victorville bound BA 763s when they were brand new.
