Well, I bit the bullet and ordered one today. I emailed a bit with David from Entacore, and he said it will be ver 1.3 (ver 1.2 is currently listed on the website.) He noted increased soldering reliability, improved RF shielding, and new software to be released in the next few days.
I'll be sure to post a full review when it comes in; there's still not a whole lot of info out there on this unit.
