I say "new" because what is really new on it? It's just another re-configuration of existing options.
The Seventy-Two reminds me of my 2004 XL1200C with the chromed out engine, narrow front-end, and 21" tire up front. I think the Seventy-Two is decent-looking... for a stock bike. I'm not a fan of the 2.1 gallon tank though. It's not practical and, visually, it just looks too small against the frame. I think a 3.3 would have been a better choice.
Looking at other options in the Sportster family, I really don't like the wide front tire and front-end found on the Forty-Eight or the new Custom. I don't like the dark gray engine on the Nightster. I find the XR1200X really interesting but I can't imagine buying one. Out of the current lineup, the Iron is my favorite, but I'd have to do a 1250cc kit immediately. While the Iron is my favorite, I would say the Seventy-Two is now my second-favorite Sportster in the current lineup.
With any luck, the "new" Seventy-Two will be at the Progressive International Motorcycle Show this weekend so I can see it in person. If it is, you can be sure I'll post pics.
Until then, here are a few more from Harley's website:
