Just thought I would give an update as it may make things calmer! Well non of us want a panic. Anyway I was in the same situation with the withdrawal of btc not happening, but given all the comments decided to risk transferring some more of my coins. Well I thought if it is a disaster it makes no difference. So the good news is just withdrew some more coins with no problem at all.
So having read all the comments it does seem to be a glitch which mtgox is working on, and given the number of backlogs, no wonder they have no time to reply. I am not letting them off as they should be more transparent.
Just FYI I decided to with draw in 0.2 increments!
I also think the issue on Sunday was compounded by what looked like a panic
