If the new upgrades in Threshold anything like the systems they used for dogfeeding before, then the new upgrade experience will be as streamlined as on OSX.
I use VHD boot sometimes, but the problem with it is that you can not run your main system and your testing system simultaneously. That is the biggest drawback for a lot of people I think, but the performance is indeed much much better
WZOR has claimed that Windows 9 will RTM in december before, but given that it is scheduled for a Spring 2015 release I don't think that's correct.
only reason I could imagine to do so is that they want to get rid of everything read 8 or 8.1 and hit the x-mas market as soon as they can even if the software is kind of buggy. Since 9 probably is a feature blown up 8.1 with a new kernel, it really can be that way and they let it run as the preview just to find out. Update cycle is announced to be short so they can release more features next year and so on
I think some of the OEMs were not too happy with the spring launch date. I can see their point, lets get 9 on machines in time for xmas shopping. ETA - I want to get it on my machine now...
