I don't think for one second that Q would be leaving and not posting again.
Q is a leader and a leader doesn't just disappear on his team. Comms / posts were terse towards the end and I believe the posts were either communication between Q and another Q team member, or with other parties, including Edward Snowden. It felt like a negotiation was happening. When Q returns, it may be as Q, but could very well be as just another Anon on 8chan qresearch providing a tip, an article a connection. He'll be back soon, I'm 100% sure.
