QA is one of the worst things to be doing in this environment. Like if you actually have a problem it's so much easier to be able to get someone to just come there and look at it, maybe take the mouse. No amount of screensharing, modules to split control, sending screenshots, calls or IMs will really substitute that... The virtualization in particular is going to suck if they said they are already having hardware performance problems. Nevermind the compromises to the shared testing environment. Especially since this is the patch with the ARR revision.
Basically 2 months behind schedule which will have reverberating effects on the next patch and the expansion cycle as a whole. It's unfortunate but it is what it is.
