Ehh.. The final version is released for public on 26 October 2012. Before that it was only available for MSDN subscribers. And - yes.. there was a consumer preview version available on 16 february 2012, but that version was not really the same as the final version (as an example - you could still use the aero transparency in the preview version, but in the final version it is disabled). Anyway - there is no guarantee older plugins/drivers will work good with the FINAL version of W8. My advise is to try it out, but be aware some things could not work - and it is possible they will never be upgraded... that's all. I have been working as troubleshooter in the IT department of a large organization, and it was common practice to test all possible combinations of hard- and software for a 6 month period, before rolling it out in a "mission critical" environment. I will admit this practice has become standard for me, and it has some influence on the advise I give here... sorry about that..
The plugins I have installed work. They run the gamut from Ozone 5 and 4 to Kontakt 5, Battery, Steven Slate Drums 4, BFD eco GPO, Melda stuff too. Also Moog Mod 5. Oh, as well as Nugen 32 bit plugins. Not one plugin I have tried has failed. The only caution is be sure to have Windows 8 hardware drivers. X2 Pro is solid as a rock so far on win 8.
One thing I have looked out for in this forum are negative posts from Windows 8 users. I have seen none. Its the ones that don't have it that cation not to get it yet. I wonder why that is?
Use your common sense here and try to list error reports due to running Windows 8 and X2. Its great to be safe with an OS. Its another thing to be paranoid. Because I had the opportunity to test it well enough before I bought it and fully committed to it I am rather confident with it.
We all had that same opportunity if we chose. I think its time for the uncommitted to sit back and see what the results are before giving advice about it.
