More stuff is always good. But yes I'm afraid that the release in August will not be met or the release will be, as it once someone else, in another thread, so beautifully formulated only a Patch 10 aka Beta 1.0 just extended to the fully accessible game content.
BTW: Wrong subforum...

That's basically Larian model anyway. They always overpromise and underdeliver because they waste time adding meaningless fluff.
They've already reneged on all classes being in EA by not having time to roll out Monk.
Their full releases are full of bugs and broken features that take a while to fix and then their Definitive or Enhanced Editions ~2 years later are the real working game.
Anyone expecting to play BG3 on release date and have a smooth experience is delusional.
