Hi Justin, yes a 64-bit version v4 beta release is not too terribly far off now, it's difficult for me to estimate how long very precisely so any estimate is probably wrong but my best guess despite that would be 3 or 4 months from now.

Just yesterday I've completed porting all the file IO libraries for stuff like skp, pdf, dxf, 3ds, and fbx formats. So that was actually a pretty big milestone.

The biggest single area left is the viewport display code. I have some miscellaneous loose ends to tie up first then I'll be left with the viewport display as the last big chunk of work to do.
