Front page of MacRumors says the iPhone 8 may be delayed until Oct/November:
...suppliers are encountering "technical issues" in the production of the upcoming "iPhone 8" because of differences in the display lamination process and challenges involved in integrating the 3D sensing front camera system.
The report tallies with a rumor that circulated last month suggesting the iPhone 8 may go on sale later than usual, due to the switch to an OLED display and the new technology needed. In such a scenario, the launch of an iPhone 7s and 7s Plus would go ahead in September as scheduled, with the higher-end iPhone 8 coming later in the year.
Such a staggered release would be highly untypical of Apple, and it's hard to imagine the company holding a September launch event for "S" cycle iPhones with no mention of the highly rumored OLED device. However, it is possible the higher-end phone could be revealed at the same time but launched in limited quantities or at a later date. Barclays analysts recently claimed that Apple will launch its "10th anniversary iPhone" in the usual September timeframe, albeit in short supply until a full stock arrives in the fourth quarter.
Also, a new analyst predicts the price point could come in under $1000 to compete with the S8+:
Apple's widely rumored high-end iPhone with an OLED display is expected to cost upwards of $1,000, but UBS analyst Steven Milunovich believes that a base 64GB model could start at $850 to $900 in the United States. That price point would be similar to Samsung's new Galaxy S8+, which starts at $840 to $850.
Milunovich said the flagship iPhone could start at under $1,000 as part of Apple's "mainstream luxury" pricing strategy. He also believes the 5.8-inch device will be competing at a screen size disadvantage compared to the 6.2-inch Galaxy S8+, leading him to predict Apple will adopt similar pricing as Samsung.
This is all pretty exciting for the iPhone and I have
zero doubt this will sell incredibly well, but I'll say again that it's a shame this is looking like the only way for Apple to catch up to Samsung's hardware and features: in a third, more expensive tier that is likely going to be difficult to acquire due to limited supply and possibly won't see release until later in year than we're used to for a new iPhone.
At least the 7S models are expected to gain wireless charging so they'll have new glass backs (presumably looking similar to the current glossy black iPhone 7).
Recently, Apple, in a rather rare and uncharacteristic fashion, came out and admitted they made mistakes with the direction of some of their Mac lineups. This shows something some of us long already knew: that they are fallible. That every decision Apple makes isn't perfectly thought out or fine-tuned or perfectly focused. They are a company like any other that have to make big and, to be fair, difficult decisions. This rare display of humility is something I'm personally happy to see from them. I hope some of this translates to their plans for the iPhone and iOS in the coming years.
