if schools are seriously considering your son, then they will definitely talk numbers with you. It seems he is on a long list of potentials and they are waiting for you to come back to them to say we are interested. not much money to spread-out and if they get you early, then you will get minimal money, but you will get the ability to brag that your son is verbally committed.
I know a lot of kids who went thru this and waited until their sophomore year and now they are getting the actual offers with $$ amounts offered to them
