You both realize XenForo is still in BETA, right? The likelihood of UIX.2 being released is slim. All that would do is put ThemeHouse into a pinch. Each release of XF past this current BETA, everyone who has the theme would be screaming at them to get the theme updated, that there are templates out of date, etc, etc... There is most likely going to be at least one Release Candidate, so there is at least, at a minimum of one update with them running around, getting blasted by impatient people because there templates aren't up to date, getting thrown under the bus, complained about, topics started, etc. Don't deny it, we've all seen it happen.
They release is now, to be nice, in the end it will backfire and they will be the bad guys, I can already see it.
Just be patient, XF2 Gold cannot be too far away.
I'd say there are quite a few themes that are close to being released, but by throwing them out here before XF2 Gold, they are simply increasing their workload unnecessarily.
