The costs of the electronics serving the content aren't really the dominant cost - it's the power units (those huge equipment boxes on the 777 and 767), the screen, the electronics needed to drive the screen, plus the PCU (passenger control unit). If you've got to replace all of that anyway, the cost of getting a new system versus buying a looping system is pretty minimal (if new looping systems are even still sold that would drive all of those seats).

The big reason that they weren't replaced on the current gen airplanes is that you'd have to basically replace all the seats at the same time, since the PCU and the new screens probably wouldn't fit in the old seats.

Edit: There is an argument for ongoing maintenance costs, however. As the Panasonic units in the new seats demonstrate, IFE systems are maintenance hogs.
