Here are things I know for a fact, from my connections to and experience with GW:
- GW sees most of the negativity online as a vocal minority. The issue with the internet, is real issues get lost within crying wolf. GW doesn't give those doomsayers any energy as it is counter-productive.
- GW is a huge company that isn't as savvy with their online outreach as some of the newer, smaller companies are. This is something that they are trying to fix, but its difficult to turn a freighter on a dime. They are more aware of the real issues than people give them credit for (recent 40k releases are proof of that), and I think we are going to be surprised at the final results of Fantasy.
- GW is not wanting to squat any army. They want to sell us miniatures. They just want to solve why they are not selling. There are fantasy SKUs that have not turned over for over 4 years! Key units in certain armies that they never sell. What will happen with the fantasy armies is 8th books will work in 9th, new factions will emerge or replace some of the old ones. Then if there is demand for an old faction to come back, they will bring it back and fully support it. It may have new models that are less generic looking (which is good) but they will bring back and support what there is demand for.
- 9th is going to be more fluid and still support the style of play we prefer. They are broadening WFB's market, not shrinking it.
I agree with you that D&D 4e and NWoD were correct strategies and moved those game systems forward. 4e's main flaw is it focused on the game engine and the DM first, making those run very easily, but at the expense of the player making a character that felt, well, like a character and not a game piece. NWoD's format, mechanical changes and general approach to overall was spot on, but they stripped away everything that made their world what it was (ironically through an End Times campaign).
GW may be fully aware of those missteps and trying not to make the same mistakes. We need to give them the benefit of the doubt. We have not been shown the whole vision yet. We are still in act two my friend. That's the point when Luke gets his hand cut off and Han gets frozen in carbonite, ya'know

There is a story unfolding and that involves drama.
You know, what is ironic about this, GW is shaking things up in reaction to the market. This is directly connected to vote with my dollar tactics. Fantasy was stagnant and sales have dropped. Partly because of 3rd parties making generic models, partly because of recasters and partly because of 2nd hand armies. Yes, there is the whole debate of pricing, but bottom line, financially things weren't working for GW. You can't expect them to lose money on a game just to keep parts of its market content with off-brand miniatures and purposely trying to find ways to not buy miniatures from them. In a way, End Times is a direct result of those forces in the marketplace. Then, on the other hand, many of Warhammer's fans have complained about story not moving forward and the ever-looming threat of Archeon and the endtimes. Well, here it is! You can't have story without change occurring. Nations are going to fall! People are going to die!
Any rate, GW is actually showing some balls in what they are doing. They are risking their game, its resources, reputation and fanbase to breath new life into it. They are investing in fantasy to bring in back up on par with
40k instead of just putting it out to pasture. Sure we all have invested in our armies, both time and money. But its no where the investment GW has. Likewise, when a property like Warhammer is handled by a large company like this (i.e. Star Wars, Marvel etc) there are usually control documents and style guides that maintain consistency between products over the years. GW works with those tools too. Just because old designers we like are gone, doesn't mean new ones we like won't take their place. Besides, old school GW made game design mistakes too. There are some specific ones in my mind right now that I witnessed, and they were bigger botches than End Times: Khaine.
Anyrate, just breath man, let them get out End Times: Archeon and then 9th edition and we can assess where we are at. In the meantime, play the hell out of 8th edition and enjoy it.
