I'm about to do a Java to iOS shootout, so this is fairly apposite for me. RoboVM's big advantage for us at the moment is that it's a commercially-supported product in a space where you are completely at the mercy of your tools; if your use case falls outside Google's, then j2objc is a potential cul-de-sac; XMLVM looks interesting but may still be more of an academic project than professional tool, and so on. Ultimately, it makes more sense for Xamarin to give RoboVM more resources and take the codebase internal: the end result is likely to be a better tool and higher revenue.
