My belief here is Apple is just model/feature rationing, and they also had older models they could sell.3) another suggestion was a phone with a screen closer to 5.5". My hypothesis is that didnt happen because of the china market. if apple is just going is make 1 XR, it will be larger than smaller, as the chinese market likes large screens.
Remember, they released the X last year, without the Max. Then they released the Max this year, along with an XS, and they added the XR for the mid-budget tier. For those who want neither and who want to save money can order from the 7 or 8 series.
Come 2019, the 7 and 7 Plus fall off the list, leaving only the 8 and 8 Plus for the legacy models, but then with two new complete lines, at differing price points, each with two models, those being:
iPhone XE (or whatever it's called) with 5.5" LCD
iPhone XRS II with 6.1" LCD
iPhone XSS with 5.8" OLED
iPhone XSS Max with 6.5" OLED
Pricing as follows (hopefully):
8: $499 64 GB
8 Plus: $599 64 GB
XE: $649 64 GB
XRS: $749 64 GB
XSS: $999 128 GB
XSS Max: $1099 128 GB
BTW, I'd consider buying a 2019 TennisS Max 128 GB for $1099. I refuse to buy a 256 GB model for $1249. Maybe Apple did me a favour though this year, since they pushed me to keep my 7 Plus another year, thereby allowing me to avoid all the "gates" with the XS lines this year.
