This is what I'm wanting too. The Air M1 that I bought was just to "play" with and test. I will hand it on to my kids when a real M1 base MacBook Pro 16 comes out.
Yeah, realistically speaking... I think it depends on use case a lot. Some people are justifiably excited about M1 even in comparison to their 16" MacBook, but personally, I think I push the machine a bit harder than most folks, and so I'm looking forward to a proper 16" MacBook with Apple Silicon chip that will completely blow me away in terms of performance.
M1 is competitive against the Core i9 in my old 16" at its best (no thermal throttling due to weird external monitor issue), which is already a good sign. If the next chip is a good grade above M1, plus can last up to 30 hours on battery (makes sense considering the 16" has almost 70% more battery capacity than 13") then I'll hit the purchase button as soon as it comes up on the store.
