I'm in full 6th edition panic mode. I don't want to quit 40K. Yeah, my xenos armies suck. Yeah, the prices are outrageous. But 40K will always be the miniatures game for me.
The problem is: I can't trust Games Workshop to release a good rules product. You can trust GW to release a cool model kit, but you can't trust them to release fun balanced rules. Sure occasionally they accidentally back into something resembling good (5th edition and a lot of the specialist games), but I don't think they know how to do it on purpose.
I haven't heard anything about 6th to get me exited. Then again, all I really want out of 6th is 5th with fixed wound allocation and with the standard cover save reset to 5+. Some slight revisions to make light vehicles less survivable.and heavy vehicles more so would not be unwelcome either. The core of 40K isn't broke. It's always been the extraneous details that have been the problem. Codexes have never quite interacted with the rules in a consistent manner across all the rule books. Mucking with the core rules in a big way while leaving the codexes in disarray as they are will not fix 40K. That's why I say doom.
If I trusted GW, I would be more apologetic. I'd have more relaxed wait and see disposition. As it is now, I feel like I should be hedging my bets. I should be getting ready to shelve my 40K stuff for the edition cycle.
It's irrational behavior because I haven't seen the new rules yet. But I can't be an observer in this. I've got time and money invested in this game. I want to continue to get a return on that investment by playing fun games. 6th edition feels like a sword dangling over my head. When it comes down, I might end up with a couple of worthless miniature armies. The local community could die out because no one else likes the new edition. Even if the new edition is good, I might still have to buy hundreds of dollars worth of models to get my armies playable and competitive in the new rules.
I really wish GW would mitigate this stuff. They should be previewing the new rules. Building hype. Managing expectations. Making me excited about the change. Letting me know I'm getting what I want, or at least make me think what I want is what I'm getting That's what marketing departments are for. Battlefront let people officially know 3rd edition for Flames was coming months in advance. They let people know what was changing before the book was out. They put the rules in the hands of their veteran players first! I don't expect a free copy of the new rules, but an official heads up would be better than incessant rumor-mongering in the blogsphere. Better on a galactic scale.
But maybe this is GW being smarter than we give them credit for. They know most of us will buy the new rulebook no matter what. They don't have to do anything, because they already got the core audience by the nose due to our already mentioned commitment of time and money.
That strategy seems to be working for them so far, and companies are loathe to change a working strategy(non-working ones a lot of the time too). You have to wonder how many times they can raise prices without raising value, how many times they can ignore the competition, and how many times they can patronize their customers before it's one time too many.
