Some major news in the article is that the dxf/dwg importers will be removed from the Free version of SketchUp. (The Pro version will still have them.)
In the next release of Google SketchUp, our free modeler, we've decided to remove the dwg/dxf importers. We know how important these importers are to our professional customers, especially those who depend on CAD products in their daily work. And for that reason we'll focus our attention on supporting them in Google SketchUp Pro, where we really understand all the nuances of your workflow and where we can provide professional support to troubleshoot your issues.
It seems like this is going to hit a lot of people pretty hard. The license for the Free version allows commercial use, and I would guess a lot of small businesses and individuals who otherwise could not afford it are using the Free version for business. No longer having the ability to import drawing files could really hurt.
