THere is all the incentive in the world right now for them NOT to increase the practice. From the agency's perspective, making the lines grow will increase justification for more staff. From the Administration's perspective, longer lines will serve the political ends of forcing Congress and trying to change control of congress to all D in 2014. From the paranoia side, the powers that control agency risk avoidance will think that terry-wrists will see such a step as a vulnerability and "test" the system, therefore the guard should be raised not lowered.

I would assume that Pre-Check will be one of the first areas to close.
