History shows that machines that have fixed specification get noticeable better software as their commercial lives go on as programmers get to grips with the hardware and squeeze every last bit of performance out of them.
The games at the beginning of the original Playstations life vs. games a few years into its life is a good example. Plus all the home micros from the 80/90's were getting much superior software by the end of their commercial lives.
