Not out yet. Here is when we think it lands, and exactly why we think so.

We will keep this on your list as the date moves.

Reveal

The day it is shown to the world

Good guess · Right month, maybe not the day

13 December 2026

in about 2 months

Almost certainly between 30 November and 25 December 2026 — that is where eight out of ten of our guesses land.

Where it will almost certainly land Still possible, but unlikelyThe higher the shape, the more likely that date.

Where we started Its own release rhythm This line has launched on a steady schedule, so we started from when the next one is due.

Reports behind it 4 separate stories Found across 4 articles. When several sites repeat the same leak, we count it once — otherwise one rumour would look like proof.

Since last time 1 day later Last changed on 29 Sept 2026. We recheck every day, and only write a new forecast down when this answer moves.

Where you will be able to buy it

Likely one region first Based on how this product line usually launches

This line usually starts in one market and travels later, if it travels at all.

only China reported so far.

These are the places that have actually been mentioned in reports about this phone. A country missing from this list has not been ruled out — nobody writing about an unreleased phone lists the countries it is skipping, so we cannot tell either way.
