actually he is not quitting he is getting fired due to sales execution issues - company refused to give 2014 guidance due to limited visibilty and "the need of more bookings to come in"

you don't exchange key management if things are fine or just a little lumpy - so it looks quite clear that management will take down growth expectations for 2014 during the next conference call.
given the fact that most analysts currently have a "buy" rating on the shares I would expect multiple downgrades tomorrow as these guys are also capable of putting one and one together
float of 5m
and that warrents a 20% plummet..
