I have a suggestion lok_e1...
It's Revit.
Autodesk's reality capture engine is capable of visualizing huge point clouds directly within Revit, not to mention Autocad, Navisworks, Inventor, Maya etc. They've really come a long way towards making point clouds accessible.
It's true, Revit isn't quite as friendly as Archicad, but it is very capable software once you learn your way around.
I was a die-hard Archicad user for many years, but you can wait on Graphisoft forever, or you can get to work with laser scans in Revit today.
