I am still and I would encourage others to try and remain objective on this alleged leak. It certainly appears to be a wonky translational copy and confirms a lot of the rumours that are out there (inc the fast skimmer rumoured release). However to paraphrase the legendary Sir PTerry
The difference between me and Neil in our attitude to .... projects is that he doesn't believe they're going to happen until he's sitting in his seat eating popcorn, and I don't believe they're going to happen.
Until we have the codex in our hands, this really is all just internet hype and rumour gone mad. I get the feeling that when the codex comes out and it doesn't contain the uberepixawsoomautokill character for 35 points that there is going to be a torrent of pent up fanboi backlash against GW that all this stuff isn't in the codex when most of the stuff they are hoping for is wishlisting gone mad.
