Here is an example of why I think Aquaman (original recipe) will be revived by Blackest Night. He's just worth too much to DC - both in marketing purposes and in-universe. Even if he can't carry a title, he is one of the most instantly recognizable characters in their stable. You see the orange shirt and the blond hair and you know who it is - this was probably the reasoning in giving the new Artie Joe Aquaman the same exact look but since he didn't sell/work out, I'd say its a 99% given they'll bring Arthur/Orin back.
Besides when written well a guy who talks to Dolphins, rides giant sea horses and rules 3/4 of the Earth is fun to read.
