The iPhone X had been out in the wild for less than a month when we first reported rumours of Apple's likely line-up for 2018: three new full-screen iPhones, one of them a straight replacement for the X, one a bigger version of that and one a less expensive model that sits somewhere between in size.

The proceeding 10 months have seen everything from Apple's supply line to its internal marketing leak like a sieve, muddied somewhat by the usual baseless speculation, but the line-up of three phones has remained relatively constant. At this point, it seems all but assured that, when Tim Cook takes the stage next week at Apple's big iPhone event (Thursday, AEST), he'll be introducing these three phones. But what do we know about them?

According to 9to5Mac, which also uncovered official images of the phones, the new flagship pair will be called iPhone Xs, a name that seems to prove once and for how silly it was for Apple to inject a Roman numeral into its naming scheme. The company will most likely insist on pronouncing it "the Ten Ess", but most of us will end up reading it as it's written and referring to it as "the Excess".

The smaller of the two phones is expected to sport a 5.8-inch OLED screen, making it the same size as last year's iPhone X. The larger phone is expected to have a mammoth 6.5-inch OLED, giving it just slightly more real estate than Samsung's Galaxy Note9. Also, like the Note9, it's been rumoured to be coming with up to 512GB of built-in storage.
