shepherdless you are right that reducing the magazines doesn't save all that much in printing costs because of the fixed costs involved. But it probably saves a lot in translation man hours. That's where the main financial incentive for cutting back the literature may be.
Recently they abandoned some translations altogether, included simplified French and so on. What I thought was interesting was they didn't even bother to offer a fake excuse. They just said, "the GB has decided to stop them" and that's it.
More desperate cost saving no doubt.
