Its rather besides the point. It was a clear commitment, one of which many people in the DDF paid on the basis of, to which the KS wouldn't likely have been funded without, and were getting on to a year since the game was released yet nothing - and of course the silence on this issue is deafening. I think they are just hoping it will go away. From my point of view Braben and Brookes (and I'm going to use their names rather than Frontier) behaviour on this is despicable.
When it comes to this sort of stuff, and there are many other examples, Frontier, or more accurately, the management, seem to be happy to renage on promises, and do people over, and it demonstrates an extremely poor set of behaviours and shows me at least that they have little integrity. This likely affects a very small number of the community (this includes myself) but to be quite frank I wouldn't trust Braben as far as I could throw him. Ultimately that is a very disappointing situation be in when you backed a project on good faith and you get knifed in the back. Its this kinda stuff that has soured the whole experience of ED for me, so thanks for nothing.
Lots of other examples which show they can't be trusted and without going over board I'd say they aren't particularly pleasant people. Just bad form really. They don't deserve the great community they have and due to all of this I think the only way forward would be in the courts. I tend not to forget when I have been screwed over.
They really only have themselves to blame. So shame on them, they don't play straight. Its worth bearing this in mind when dealing with them.
