Not to defend Larian's lack of communication but this is kind of their MO. Radio silence for a few months and then suddenly there will be a 10 gb patch that's like "btw we fixed 1,000+ bugs and also added some content, thanks for playing!". They don't really talk about what they're doing aside from some unofficial confirmations on twitter and maybe a community update once in a while. If it makes you feel better though in my experience the wait has usually been worth it.
