It is likely that comic shops will receive their delivery of comics early and will hold them, then will put them on sale on whatever day they are open. Could be Christmas Eve, could be Boxing Day, we'll know the details later.
But at least we know what comics they'll be, according to the Diamond solicitations at least, which may change. A reduced number, sure but big books like Origin II and Forever Evil. As we get a Doctor Who Christmas special on the TV, we get one in comics as well.
And for those looking for action figures at the bottom of their stocking, there's a Robotech/Voltron comic.
Here are the books:
