On p 178, under Spell Selection and Preparation for the wizard, it says:
"When preparing spells for the day, a wizard can leave some of these spell slots open. Later during theat day, she can repeat the preparatin process as often as she likes, time and circumstances permitting, During these extra sessions of preparation, the wizard can fill these unused spell slots. "
Then on p180, under Spell Selection and Preparation, it states:
"A divine spellcaster does not ahve to prepare all his spells at one. However, the character's mid is considered fresh only during his or her first daily spell preparation, so a divine spellcaster cannot fill a slot that is empty because he or she has cast a spell or abandoned a previously prepared spell."
Now, my PH3.0 isn't available to check, and I can't ever find this section in the srd, so I don't know if this is a change in the language or not, but it seems pretty cut and dried here that divine spellcasters either fill all their slots or they can't fill any they didn't get a chance to fill earlier. If they only choose to fill half their available slots (maybe because they're pressed for time), they can't fill the rest until the following day....
