I do not think the domain spells will be available to the cleric to memorize.
As I see it, there are no longer any domain spells. You gain both domain powers and since you gain the powers of both domains...there is no need to memorize the spell/ability anymore. I think that is why they took the +1 off of the cleric's spells per day list.
Look at the bright side...you get the 4 level 0 spells as at will abilities. No need to memorise those pesky cantrips.
You still get the spells per day (+ spells for high Wis).
You still get to spontaneously cast cure/inflict spells.
Not to mention the Channel Energy ability...AoE heal (or harm if you're a meanie)...nice! Use your spells for other things and still be able to heal the party.
And those two domains you have...Well, you get both abilities from each domain. Some of them are unlimited in use, some have a number of uses based on your level, some are once per day. In any case, those domain abilities surpass the domain spells of the core cleric class. You get both abilities/spells so there is no need to memorize them.
All in all, a good improvement. The only thing I noticed is that there are only eight domain abilites instead of the origional nine. But I can see why they lowered that. Any ninth level spell is pretty nasty, no matter the class. Immagine having two of them one time per day...
Just my take on it.
