All OnePlus 5 models go out of stock, is the OnePlus 6 coming soon?

All OnePlus 5 models are now out of stock in the US and in other markets availability is very limited as well, so... does this mean we are getting the new OnePlus 6 soon? Or OnePlus 5T?
This year, OnePlus has unveiled the OnePlus 5 in the middle of June as well, and now it's already the beginning of October, so it is possible that the OnePlus 6 or 5T is indeed in the cards.
To add some context, let's mention that OnePlus is owned by Chinese giant BBK Electronics, which owns the brands Oppo and Vivo, and with all its brands combined ranks in the top 3 of the world phone makers by volume. And its two other phone brands - Oppo and Vivo - have already unveiled their new phones with minimal bezel, and OnePlus usually follows with similar designs.
