I can't say "every", but the reason most regulars on here said September is that some time ago, that was the non-debunked (by Larian, or a publisher) target date. That came and gone. As others have said in this very post:
A) Larian has nothing to do with the release date now that they have a U.S. publisher in place
and
B) The publisher has announced via 'official PR statement' that Holiday Season is the target.
Larian is not going to say anything different. Expecting forumites not to post in a, hello, FORUM, is pretty silly. You have your answers, you just choose not to (want to) believe/listen/pay attention to them.
