For the same reason the keys are still staggered on most keyboard: ignorance, stupidity, and risk aversion. You don't need much of each: they feed on each other to preserve the status quo. Many people seem to believe that slanting the keys to the left is actually more ergonomic than a straight "matrix" design. And I think manufacturers aren't willing to risk selling keyboards that don't have the usual look. The natural keyboard is no different. They sell one idea: splitting the keyboard. The rest doesn't change because it would spur too many questions, and maybe cost them customers.
