I must admit that I'm one of those lurkers too (or better : have become one). I visit PGD at least once a day to read through all new topics and posts, but other than that I don't actually have time for more due to real-life obligations.

And yes, I'm still working on "Phase 2" (almost) every day, but I don't have much time on my hands, so though progress is steady, it's not that I'm making huge progress. And I also update the project's satus on my homepage (as well as on the delphigl forums, where it all started), but posting about progress with a steady rate and releasing videos also takes it's time, and spare time for me is something rare nowadays. So at this rate it may be finished shortly after Duke Nukem Forever gets released

Other than that I see the same thing happening over at delphigl.com, where it is pretty quiet right now, but I'm pretty sure that once summer is over more people will return to coding again and we'll see an increase in activity (hopefully).
