Word of warning: don't get excited about the interface, it's just the graphics they've chosen to use for this video I believe.
I had to temper excitement in the office as some thought that the video was indicating a new UI. VW should move in that direction.
It is a nice video. The graphics team did a good job, but it does not look as if the graphic language of the video will get rolled out across VW. The photo of the box is just using a green version of 2014. I liked the opening VECTORWORKS 2015 logo in the video. A guy in my office even comment - "Wow, it is looks like a real company now." (He is italian, English is not his first language - but I know what he means.)
Now that all the engineers have completed the 64 bit transition, maybe a interface refresh can start in earnest.
