I’m not FatSharkCatfish to answer the question, but don’t you think that if FatShark had even the slightest intention of communicating something on the subject, or simply explaining the delay, or at least apologizing for it, that this wouldn’t have happened by now? I mean the letter was delayed for at least 2 weeks and the content is just PR babble that you can type up in 5 minutes. I would also like to get at least a statement on the rough roadmap but I think it will:
stay with this statement… which says what is being worked on but doesn’t even roughly outline how FatShark envisions it now. At least, it can only get better 
I just hope, since they also write that they want to listen to feedback and deliver ‘a’ complete crafting system (which can also mean that they don’t necessarily continue the current one… hopefully, but a version adapted to the feedback) and adjust the progression, that the delay - especially in crafting - is simply due to a more extensive rework. But this is also pure wishful thinking / speculation due to the meager information available.
