I agree as well, except that we don’t have until April to get this done. We were supposed to be finished before the New Year so we are already behind.
Much more important to consider is how much the new Codex will actually affect the Grey Knights in BFG, which is far more vast in scope than anything in WH40k. Grey Knights as written in the Inquisition rule-set are already pretty powerful, and it’s hard to add much more to them without turning them into Necrons!
A case in point is the recently-released Dark Eldar Codex. Everyone agrees they needed a reboot, and that’s certainly what they got- they are better in almost every single respect in terms of technology, weapon choices, elites choices, etc. However, for all the improvements, the only thing that would have any affect in BFG terms is possibly the “Power of Pain†rule in regards to boarding actions. Sure all the new stealth tech is nice, but trying to scale that up to BFG terms to make holofields even more potent is simply fanboyism. Now is the Power of Pain worth addressing in the FAQ? Possibly, and we may do so before shipping the FAQ off to GW since we are planning to incorporate small corrections, formatting and line art improvements anyway, but is it really worth it?
The only thing I can think of that would be a game changer in BFG terms is the Grey Knights officially getting battlebarges, which I don’t see being addressed in a WH40k Codex anyway. With all the ways these ships can already be used, I don’t think it’s worth the risk of getting this whole project turned off in the hope that Grey Knights can have battlebarges. If someone wants them so bad, just house-rule it in. Nobody says you can’t.
If you REALLY want to be worried about something, I’d pick the recently-released IA10. For upwards of $75US, this book devotes only six pages to Battlefleet Gothic. If the Taros Campaign is any guide, getting these rules incorporated into the BFG canon is going to be a fun ride. That’s if any new models are even produced- they have been promising a whole collection of new models for BFG since 2004, but we haven’t seen anything since the Tau fleet. Of course I would love to see some new models come out from Forgeworld, but at this point I will be happier when I actually see it.
I’m also worried about how “new†the new rules will be. The Badab War didn’t really introduce anything fantastic in the way of ships besides a war between Space Marine chapters. I’d hate to drop all that coin just to find out they re-hashed rules right out of the rulebook and Armadas. Seeing as how the example page for the Cestus Ram refers to Imperial Shark AB’s in BFG as boarding torpedoes, I’m not holding out a lot of hope. Even if the rules are new and based on past experience, the HA’s will probably take whatever Forgeworld prints in IA10, call it official and be done with it.
