Movie favorites

I just watched Terminator 3 and wondered will someone make another terminator movie that will be one of the classics i.e. "Terminator #" that could go on forever. What do you think?
I think it all boils down to:

movie = "Terminator";
i = 0;
while (PeopleWillingToPay(movie, i))
  Produce(movie, i);
  CashIn(movie, i);
as long as the co-actresses look sexy and a plot evolves I am willing to watch it is on the things I pay for monthy lol I like the classics
