Thats what I originally thought as well. I personally think some of the substantial authors of the series have been fatigued by all the crap thats been made and have turned their attentions to better projects.Seriously, the whole HH series could have been 7 to 12 novels. By Novels I mean, Game of Thrones style ones. Big ... lots of content, each being top sellers. That would be just for the main story arc. By all means release side Novels, perhaps 1 for each Legion so that fans don't have to suffer by not seeing their favourite Legion.
30+ books and being swamped with Shattered Legions and Calth at every turn is dull and boring.
I also believe BL need to pull their head out of the sand. It's not the 90's anymore, we're in the digital age. These books need to be primarily sold on eBook format, no printing costs also saves money but more importantly it means that the consumer doesn't have to end up with a book shelf of a ton of novels of all different sizes. It is completely ridiculous.
On a personal note I do believe they should ditch the table top and go digital with a decent pay as you go MMO game that's actually developed, but that's just personal preference. Again, only purely because it's a digital age these days, toy soldiers doesn't tend to impress anyone, but saying you've read a "Game of Thrones" best seller and people are interested. It should be the same with the HH ones.
