I don't think it can be good news at all, because the way Karpeles seeks to isolate himself and staff from any possible confrontation implies that he knows things are going to get much worse.
The lack of the usual reassurance that "Bitcoins have not been lost and clients' funds are safe" (even after Bitstamp made such a statement) implies some large losses and suggests they are focused on protecting themselves from provable allegations of fraud.
Still, for the longest time, Gox has specialized in impressively minimal customer communication.
If they were going to get better then they wouldn't need to do this. It seems like a pretty insane time to be spending time on an office move instead of on fixing the issue - unless a fix is hopeless.
Unless perhaps people at the company are being threatened by angry customers?
I'm sure the servers will be in a datacentre that's not even on the same continent as Karpeles - I haven't looked. Due to the constant technical and (software) security issues that MtGox has had then no doubt their security isn't the best, but at this point I suspect that is the least of their worries.
Most likely. (I was also concerned with random notebook computers that may now be on the move.)
Offsite servers are at risk of inspection/manipulation by the hosting company's employees -- people who have been becoming ever more aware of how lucrative bitcoin theft could be for them.
