I think they will release it before the first expansion, but even if they don't I have no problem waiting.CDPR has showed a remarkable will to listen to fans an try to further improve their game. Storage chest, inventory changes, NG+, Triss fixes were all mentioned by the fans, it wouldn't surprise me even if they add some changes about other stuff people gave mentioned on these forums. But again, it is important to be realistic about demands, I'm sure not everyone will be happy about Triss changes when they eventually come, but for me personally whatever they decide to add, it have to be enough.
