In a way, this is an entirely natural phase (and it is an end-phase) for any forum.
That is, you run out of substantive things to say - and so degenerate into either endless sniping (which is what always happens on Usenet and which seems to have happened here) or you start talking about endless (but, luckily, pleasant) off-topic things like birthdays, pets, gardening, Doctor Who, what browser you use, what you had for lunch, and so on. As I say, one or the other...
Here, I think we've exhausted everything there is to say about the Pi, that can be said when no one (or almost no one, if you want to be picky) has one and no one (or almost no one, if you want to be picky) expects to have one any time soon. I don't even want to hazard a guess as to when someone will have one, given that there are estimates (sourced from RS/Farnell emails and god-knows-what-else) all over the block. At this point, March 1st, 2013 is looking as good as anything.
Now, mind you, I'm not complaining. I've said from the beginning that the only sane approach to this is to just sit back and get it when you get it.
But again, to re-iterate, I think this is where forums always end up, when the thrill is gone...
And some folks need to stop being fanboys and see the forest behind the trees.
