I completely agree. I came for the 6XX a couple years ago, but I stayed around because there were interesting discussions and knowledgeable people. Oddly, I found things to buy in the process. Hard to imagine having that experience with this design, and I think it's ultimately going to harm sales.
It feels like a consultant got ahold of somebody and convinced them to spend gobs of money on a new brand. Whatever the reason, what was delivered was a less usable site, a less distinctive brand, and a less accessible community. Bummer.
