Launch of iPhone XS, iPhone XS Max and iPhone XR led to the removal from Apple's offer of two iPhone models that were still recording fairly good sales. More precisely, the iPhone SE and iPhone 6S were removed from sale by those from Cupertino, and of course there is no need for any explanation for the decision taken by them.
The iPhone SE was released more than 2 years ago by Apple, and the iPhone 6S more than 3 years ago, so it was normal for both to be discontinued by the Americans. Now the iPhone 7 is the oldest iPhone model that can still be bought, while the iPhone SE and iPhone 6S may still be available at some partners, but not directly from Apple.
The iPhone SE has disappeared, but the iPhone 7 is sold at the price of 449 dollars by Apple, 100 dollars more expensive than the smaller model, but the difference is that it has a much larger screen. Considering that the iPhone SE has disappeared from Apple's offer, it is quite clear that there is no longer any intention to launch an iPhone SE 2 too soon.
UPDATED: and the iPhone X disappeared from Apple's offer.
