I agree with #2, it has been quite quiet around here lately. I'm sure it will pick up the closer we get to GW2. Generally if any tasty morsels of info are dropped by ANet there will be a spike, but I expect it will stay for the most part this way until GW2 is playable.
As for guild activity I mirror Photics' sentiments. There's just not much motivation for us to continue with GW1.
.. but just you wail 'till GW2 alpha starts up
