Personally, the new 14" and 16" MacBooks will have the iPad Pro (2018) design language, but will include the following features:
1. Apple M1X SoC with more CPU cores and more GPU cores.
2. 16, 32 and 64 GB of RAM available.
3. 256 GB, 512 GB, 1,024 GB and 2,048 GB of SSD local storage.
4. Touch Bar replaced by function keys. There will still be a fingerprint sensor for Touch ID.
5. Mini LED display panel, and 720p web cam replaced by 1080p web cam.
6. WiFi 6E support.
7. Right side of laptop will have one USB-C Thunderbolt 4/USB 4 Type C port, plus SD card reader and HDMI 2.1 port.
8. Left side of laptop will have two USB-C Thunderbolt 4/USB 4 Type C pots, plus (maybe!) a MagSafe charging port that looks like the old MagSafe port but physically smaller.
I have my doubts about the MagSafe port, especially if Apple can get the USB-IF to squeeze more charging power for USB-C charging over USB Type C very soon.
