Universal 3D engine

Hi all, I am new to MonoGame, looks very cool. I come from a iOS/Android background and want to try to create something 3D that is cross platform. Xamarin recommend using you.

However, the 3D samples use XNA, which I read somewhere, is what your moving away from.

So my question is, if I am wanted to do a 3D cross platform game, which should I be using in Monogame
