[Edit: Had to do some housekeeping here unfortunately. As I've said previously, feedback, including (often especially) criticism is fine, as long as it's meaningful and civil. In this case, all meaningful information from both sides was covered in the first few posts. After that it was effectively just spam. Voicing issues with the game is fine. Continuing to do so after I've made my position clear, in an attempt to harass me and/or the fans of the game, is not. ]
[Edit the 2nd: Appreciate the support and reports(!), but I'm going to leave the rest of this up as the information may still be useful going forward.]
There's a modest delay, yes. Early access has always been only real reward for the SubscribeStar supporters, and this in particular was announced quite a while ago, shortly after GT first came out, so it shouldn't come as a surprise. Early access for monthly supporters followed by a later public release is a fairly common model, and the wait is often considerably longer than two weeks. Everyone who bought the game will still get the new pack, a considerable amount of new content, for free. They'll just have to wait a little longer.
