Under full assumption of good faith of everyone involved, I would also like to say that I find the fact that 3 out of 5 current Wikimedia Board members (or 3 of 4 active ones) are founders of or working for the for-profit Wikia.com, which hosts gameinfo.wikia.com (a wiki for the kind of game guides that are being removed from Wikibooks), somewhat problematic. Jimmy himself going into Wikibooks and effectively making policy is even more worrying (I know he would argue that it's been policy all along, but the fact is that these guides would be sticking there without higher intervention).
There's another GFDL wiki out there, strategywiki.net, for these kinds of guides. Given that StartegyWiki is more active than GameInfo anyway, I would be more comfortable with the whole situation if Wikia made a deliberate decision of its own to move guides from GameInfo to StrategyWiki. It seems like a good free content thing to do (build communities wherever there's the most activity), and would alleviate concerns about outside appearance of the whole thing.
I also reiterate my suggestion to rename Wikibooks to WikiTextbooks.
