Flash doesn't have support for 3D hardware acceleration. We're rendering up to 100,000 polygons per second; the maximum flash can handle is around 5 to 10 thousand. Java on the other hand supports all of this, has a great threading model, and will allow us to use direct GPU programming in the future. In addition, when Flash does start allowing 3D acceleration (as has been seen in some old Shockwave prototypes) a permission box will still be required (as Flash by default is also sandboxed away from the videocard). While I love Flash for what it does, it simply isn't the platform of choice for 3D.
