As you see on this part of the image it seems that this subdivision surface system can handle polys with more than 4 sides (which is the limit in LW). And if you take a look at the file format slider in the interface on the different screenshots, you will see that this possibility is linked with a new one called ".nxs". Otherwise on some screenshots you will see that Modo can also handle ".lwo" file format with objects composed of 3 to 4 sides polys only.

Interesting !!!
