That prediction has been around for years since Apple recycles old bodies and this is the next in line as nobody expects Apple to recycle the X which set foundations for the more expensive Pro line. So, unless they change the recipe, it is to be expected. The question is how old is the chipset going to be since not even the regular 14 has the latest model.
The Apple iPhone SE (4th generation) will apparently be based on the Apple iPhone XR. The claim was made by YouTuber Jon Prosser in a recent podcast during a segment about future iPhones. If this is the case, then the iPhone SE 2023 (or iPhone SE 4) will not feature a home button and should offer much better battery life than the iPhone SE 3.
