I don't know anything about that, but if Kuo says "second half", I would trust that. Meaning either:
- Apple either delays the next MacBook Pro revision until then. If "second half" ends up meaning very late in the year, Apple might skip a CPU generation and go straight to Rocket Lake, which we don't know much about yet. But it'll still be 14nm. There won't be a 10nm chip appropriate for the 16-inch this year. (Or, wild card, Apple could go AMD!)
- Apple ships around May, as I said, and the mini-LED version comes in the revision after that next year (meaning Kuo was too optimistic).
- Apple ships two revisions this year. Possible, but Apple typically doesn't update that often.
If at all, not until very late this year.
This is all for the 16.
The 13 is more interesting. Keep in mind the 16 just got a big set of improvements last year. The 13 hasn't yet.
Apple will almost certainly replace its keyboard. They'll also probably reduce its bezel. And my guess is they'll move it to Comet Lake-U, which would allow Apple to offer six-core CPUs on the 13-inch for the first time, and also allow them to go beyond 16 GB memory. Up to 64, but I'm guessing Apple will only offer up to 32.
I can't say much about that, but keep in mind the display portion on MacBooks is very thin. There's only about 2mm thickness for the camera module, if they don't want to make the entire thing thicker. Contrast that to the front camera on an iPhone, which is 7mm thick.
So don't expect MacBooks to have anything remotely close to the camera of an iPhone any time soon.
