Sadly I can see it going the other way, with the integrated schools surviving on the "daddy i want to be a pilot and this nice man from oxford says the only way to do it these days is to give him £63,000" brigade.
It will be the smaller schools with more prudent, but less well off, customers that will fall by the wayside.
I really hope this isn't the case but i can see more elitism and "not what you know, but who you know" on the way.
