Mea culpa. T'was a practical joke on my part, to be played on the online 40k community. I thought you might want to know, having thrown a little bit of weight behind it. My intention with this message is to keep you well-informed as always, and perhaps to pass along my regards and best wishes to your contacts in GW.
And to be clear, I have heard nothing about the direction the new Tyranid codex is going in, if it has even been started. There is no leak, at least not to my knowledge.
I've had my laugh at Warseer's expense (as well as DakkaDakka, Heresy Online, and others), but the joke has not quite run its course yet. I expect to be outed eventually, but I'd like it to be by the real rumors.
I would humbly ask that you let the document stew. There was a fair bit of positive response, and I'd like that to be carried over for a while to come. Keep hope alive, so to speak. I kindly ask that you let it be debunked in good time as actual rumors about the new codex come out. Some of the positive response may be due to the conservative (high) points values given to many of the models and options in the codex, but I honestly believe that people appreciate some of the basic design decisions made in the "leak". From now on, I ask nothing more then silence.
Now, understand that it was in no way my intention to violate any copyright laws. To that end, I made sure to change things drastically enough that the document would be useless to someone trying to come up with a Tyranid list for the current edition. Literally no unit is the same. Similarly, I posted no background material for the units, nor did I use any Games Workshop letterhead, images, or watermarks. The names of units were used, but that was unfortunately unavoidable. I sought no profit from this.
Boy, I hope GW legal has a sense of humor about this prank.
My intention was, from the very beginning, to have a bit of harmless fun, and maybe (just maybe), give the current codex designers a taste of how the community would receive the changes I proposed in this document. Hopefully this document could even offer some suggestions as to where GW might go with the Tyranids. I would love it if something truly positive came out of this. To gauge the response, however, I'd like the authenticity (or lack thereof) to remain a secret for now.
I don't actually know where GW is in the production phase. It may be too late to do anything about it if we see a December release. If so, then whatever. I'll live with it. I just hope they do a better job then I did!
Once more, this is all in good humor.
Regards and best wishes.
