Unity 5 Pro just went into beta. Anyone who has a pro license can get it right now. That leaves me out of it for now as I only have a Pro license via Nintendo and that doesn't quite count. The good news for me though is that Unity announced at Unite 2014 that Unity 5 would be coming to Wii U developers soon after its release. So, I'm really looking forward to all the performance enhancements, improved physics, and new shading technology.
