It doesn't make any sense.I would imagine tomorrow will go something like this:
"Introducing the new 16" MacBook Pro, now with 10th Gen i7 and i9 and AMD Radeon Pro 6000M series GPUs"
Why would they announce a new Intel MBP 16" and 10 minutes later render it completely obsolete in the same event by presenting the new Apple Silicon notebooks?
If any spec-bump on the Intel 16" is ever gonna come this year (I have big doubts), they won't even announce it in a press release, let alone in an event dedicated to the future of Apple notebooks.
