In ATL and ORD, you certainly will. During the busy periods, I've seen ATC issue takeoff clearance before the mains have broken ground.
On a tangent, LGA used to say "LUAW, spool 'em up" or "LUAW, be ready to go". I haven't heard them say that in some time, but it's not uncommon to be in position with the engines spooled up before the clearance is issued so that the brakes can be released ASAP.
