UA makes a distinction between qualifying and supporting systems. Sonar, Ableton Live, Studio One Pro, etc. are still supported and UA does test those and other programs for compatibility.
Qualifying is apparently a process that takes months of man-hours where UA tests every parameter of every plug-in. They chose three "test beds" for plug-in qualification: Cubase for VST, Logic Pro for AU, and Pro Tools for RTAS. So, what they are basically doing is qualifying operation of the plug-in formats. I can't argue that those are extremely representative programs, as Steinberg invented VST, Apple invented AU, and RTAS is the"Pro Tools format." As a benefit of using these programs, it allows UA to guarantee that every parameter of every plug-in will work with those particular programs because they were the test beds.
However, in theory VST is VST, and if a plug-in works perfectly under one VST host, it should in theory work under other VST hosts. So, UA does less rigorous testing with other VST hosts to check whether the theory holds true.
So far, my understanding is that UA has not found issues with VST support on other 64-bit hosts, but they are actively seeking any reports of problems from users of non-qualified 64-bit systems so that any problems can be addressed.

Exactly this, most plug-in/add-on developers have to develop on a limited range of Software it isn't possible to develop on every available DAW out there, sometimes the 3rd party developer will enter into a marketing arrangement which means they would recommend a DAW that is part of that arrangement, so what that's good business. Sometimes it can be simply because the plug-ins have gone through the most severe testing on the platforms they develop on so they can offer a greater guarantee that things will work on that specific platform and are wise to inform potential customers of that fact.
Having said that for any plug-in/add on developer that uses the ASIO or VST standard technology for their product would be commiting financial suicide by limiting their market away from the rest of those platforms that also support these technogies.
It ain't gonna happen. Whatever platform a plug-in developer favours they will all do their utmost to maximise the market they have by being pretty darned sure it's going to work on the rest and will do whatever is possible to get your stuff working on your DAW of choice.
The market is too small for them not to, I see no cause for concern here and I'm certainly not experiencing any issues currently that would make me fear otherwise.
Thanks to Craig though for wading into this one and putting some realistic perspective on it. Much appreciated ol' fella.
Further to that, also it's fantastic news that they've gone 64 bit at long last because it least means they are intending to stay around long enough to get a return on the investment of doing that and are not planning to disappear off into iOS land any time soon.
Given all those things I think it's given us UAD owners far more security than we had 6 months ago, it certainly doesn't seem to me to be the time for the fear mongers to take centre stage at all.
