Should I get the Iphone 8 plus?

I don't want to buy a phone that is $1000 which the iphone x because there the same thing, but should I get the iphone 8 plus or wait which iphones are going to come out in september?

By the way, I had never owned a iphone

IPhone 8 plus and iPhone X isn't really the same thing, if you think it is then you don't need to wait until September as you might think they're the same as well.

If the iPhone 8 plus is what you want then you might as well get that

The X & 8 Plus of course aren't the same thing. Things like the display, display size, battery size, etc are different.

As far as getting the 8 Plus or a 2019 iPhone, its simply up to your level of patience. They of course would be better but how much better & if those eventual differences would matter or not to you.

The expected 2019 lineup is
5.8" iPhone X (2019)
6.1" iPhone '9'
6.5" iPhone 'X Plus'
