I'm probably just clutching at straws now, but maybe Zel is finishing SG off, and is leaving PC for a while to build the tension, That way when he comes back, everyone will be going nuts because:
1.ZEL'S BACK!
2.SG IS FINISHED!
I mean, I think it makes quite a bit of sence, since he's been working on this for years, surely he'd want to finish it in a big way.
I hope thats true, and more importantly, I hope Zel's OK.
Maybe he's got a new profile, under a new name, and he's looking at our comments, to see if it's worth finishing Shiny Gold. Well, whatever the problem, i'll always have SG on my laptop, whether a new beta is released or not.
