Apple Watch 4 Rumors

On the upcoming Apple presentation expected this fall, presumably on September 12, all of us are waiting for the New Series 4 Apple Watch. Recently, a Reddit user stated that several Apple Watch Bands have been removed from Apple Store. And this usually happens when
Apple is preparing to launch a new line of accessories. Same thing happened June 2016, February 2017, and May 2018 as well.
On August 21st Apple removed 14 different Band models:

Sport Loop
- Marine Green
- Hot Pink
- Flashlight
- Tahoe Blue
- Midnight Fog (Nike)
- Cargo Khaki (Nike)
Sport Band
- Marine Green
- Sky Blue
- Denim Blue
- Red Raspberry
- Lemonade
- Cargo Khaki/Black (Nike)
- Barely Rose/Pearl Pink (Nike)
- Black/White (Nike)

Also, bunch of others Band are unavailable due to soldout.
But unfortunately, this might be only due to a new lineup release for the Bands themselves only.
Well, we don't know a lot about Apple Watch 4. Ming-Chi Kuo actually mentioned a few time that the new model most likely will become more rounded on the edges and the screen will be increased by about 15% thanks to the smart edges.
