Well, unfortunately the fillet probably won't make huge leaps and bounds in improvement by the V1 release. There will probably be some progress from fixes made by the guys who provide my geometry library, but it will be something that will likely be incrementally improving over a pretty long period of time.

It is a very difficult area to nail down really well, especially in places where a bunch of things are coming together.

MoI should handle relatively simple cases well, but if you really need to do a lot of more complex filleting where MoI isn't handling it for you, you'll probably need to look into one of the more traditional solid modeler tools like SolidWorks, Alibre, Inventor, ProE, SolidEdge, etc...
