Nero is currently working for the Ironworks (Jessie hired him to get back at Cid since she was getting tired of Cid using Ironworks money to fund his personal projects. Nero's apparently getting paid 4/5 of what Cid is getting paid for the Omega job.). Cid, Biggs, and Wedge's reactions to Jessie managing to do that are hilarious. Nero's also not as abrasive as he was in previous patches. There's one point where he compliments Wedge on an engineering job in the Deltascape and everyone else gets minor brain breakage over the idea of Nero admitting someone else did a good job. So yeah, he's one of the more active characters in the Omgea story and will probably be here though the end of it.
