I don't care why they do it, I just find it insulting, that any news or WIP pics or information for what's coming up has been clamped down on so hard by the draconian dictatorship behind GW's facade.
It shows that the fans here on these forums, and others like it, the ones who love GW's games, models, stories, and everything about the hobby, who pay GW their income, who are GW's Base, their life blood and very existence... are treated as either A) Enemies, to be wary of, despised for any victory they might achieve (ie. leaked pics or rumours), OR B) Suckers to be exploited, ie. manipulated by marketing strategies aimed at insta-buy hype.
I don't like being viewed that way, especially by some monstrous corporation.
Just be human, be open, and let everyone in on the deal.
I've been out of the hobby for the last 3 years or so, because the Chaos Marine Codex was so lacklustre, and I don't care for any other races - but with Chaos coming back, the few leaks that have come out brought me back to see what's up (though it looks more like they're merely finishing off the 'half-job' they started with the last one. I still don't think my Lord will get a Retinue - but Cultists are coool.)
Yet at the store there's nothing, and noone's talking.
I didn't even feel like talking to the staff at the store (what's left of the one's I used to know since they've just sacked all the casuals), because I know they're bound by the same GW policies - and so I view them with the same suspicion they view me (What am I doing back? Am I gonna try and pocket something?) If you bring up anything 'coming soon', beyond what the current WD reveals they clam up.
I hate secrets and I hate being manipulated - I'm not an enemy - I'm a customer.
