A few current problems with 72Hz:
1- Available interconnect standards don't support the bandwidth
2- Clock rates are significantly higher, demanding much more expensive
design methodologies as well as high-cost chips
3- There are no off-the-shelf devices that can do it, therefore, everything
is custom, which means expensive.
4- Up and coming LCD display technologies can barely do 60Hz legitimately,
much less 72Hz (due to pixel response time).
5- On a number of display technologies it becomes a tradeoff between frame
rate and such things as dynamic range, average brightness, viewing angle,
scan precision, etc.
