I sincerely hope you're right. I have a 13" Intel MBP that's rapidly becoming obsolete (Thank you Apple!), my complaint now with my MBP is ironically, it's size. As my (old) peepers get even older, they don't function as well. If Apple comes out with a light 15" MBA I'll probably snatch it up, depending on weight and price. Then I'll see if I can compete with a frisbee using the MBP.Thin as a paper, perfect for traveling and overall continuity!
This 15" MacBook Air will be the product of the year in 2023. Mark my words!
