I highly doubt that Superman will develop a vast array of powers in the DCnU outside of that which he already possesses. His edge lies in his methods of utilizing his powers in different ways. His heat vision can be used offensively, as a surgical tool, mechanical repair, etc. but it's still heat vision.
Every power he's developed is the result of an activated metagene, a mutation caused by yellow sunlight. The reason he stopped making new super powers is perhaps because of A: psionic mental blocks, and B: his exposure to yellow sunlight. If he were to become extremely aware of his solar-genesis, he could manipulate it - gaining new powers without even going sun-dip - that's not an option because it will force him to become an energy being as the yellow sunlight causes supercharged mitoses and then apoptosis, and cell death. It's not impossible that he could develop some conscious influence over his genetic structure, given Kryptonians have done other telepathic things, like H'el manipulating Superboy's DnA and atoms. It's not impossible either that he's developed or could develop radio-solar awareness like in All-star Superman, making him a non-corporeal matter and energy manipulator - also able to manipulate his DnA.
