Try Viz' website. O r check either AnimeOnDVD or ANN for their press release archive (encyclopedia) and future release schedules to see if it is present. If its not in any of those sources then *nobody* knows. Perhaps they have not scheduled it yet.
I personally don't know if Eva 10 is even out in Japan yet. I know that 8+ isn't being done by the original author ...
I don't know how long it takes to translate & release the manga over hear, but I don't think it can happen quicker than 6 months after the release of the japanese tankobun, and generally it seems to take a lot more.
