If I'm remembering right, the Ptolemies have Antioch and retain Tarsos. However, I gave Mazaka to Pontos after the last war with the Seleukids (as punishment, and in the hopes of getting them fighting each other), so I no longer share a border with the Seleukids. Pontos also took Ani-Kamah recently, so they share a border with the silver death. I think I can handle sharing one with the Ptolemies after I take Side, besides they'll be a more active belligerent than the Seleukids were.

I don't think Pontos and the Ptolemies are allies. That'll be something to watch for. Pontos don't have Trapezous, it's Eleuetheroi. I just put a client ruler in Sinope (did a settlement swap with Pontos, who'd just taken it).

The Bosphorus is Eleuetheroi. Pantikapaion and Chersonesos have massive stacks inside and stone walls, and there's a full-stack rebel army wandering around Crimea as well. AI Sauromatae have given up on it, I think. Olbia, and Kallatis are still Eleutheroi as well, though I've taken Byzantion.
