I was able to install and run V7 on an Epson 3800 yesterday. I had an issue with the Canon (I think I need an additional code for the dongle and I'm checking on that).
I had an issue trying to print an untagged file for building a profile however and again, I'm checking with the company to see if I'm doing something incorrectly. The new UI is improved and it seems a lot faster (maybe it's Intel native, I didn't check). But this pup is real and I suspect you'll see it released 'soon' (in quotes on purpose <g>)
