I agree. They are not romantically interested in anyone because they cannot love themselves, so they can't really like anyone else either. Analyzing exactly why that is the case is what makes their relationship interesting, them failing to reach out to each other allows the narrative to explore its themes better. By EoE, of course, they have begun to show signs of change, but they are not done yet. That might or might not imply romance later, but they are still going to have to deal with each other regardless.

Rebuild is a different case though, I am not going to dwelve too deep but whereas they were equals in NGE and even in 2.0, in 3.0 Asuka is more mature and experienced than him, and acts a lot more like Misato, demanding him grow the fuck up and take responsibility for his actions. I imagine in 3.0+1.0 she is going to have a much larger role overall and play a big part in helping Shinji recover.
