You dramatically over-estimate the pace and degree of improvements in aerodynamics, if you think it's likely you can use it to credibly justify an annual bike or wheel replacement with a realistic promise of more speed.
The big revolution in cycling aerodynamics came when the industry actually started considering that it was relevant, and started applying straightforward principles to various elements: position, bike frame, wheels, clothing, helmet. I'd suggest that not only won't there be any performance "game changers" in 2021, but there may never be further performance "game changers" unless they are the result of rule changes. I mean you can certainly change the game by allowing faired recumbents, but as things stand...... not so much!
I'm not saying nothing will improve, just that the rate of change and degree by which they improve are likely to be modest. This is already the case and the rate of improvement will likely continue to slow.
Gradual, barely noticeable, incremental improvements are likely to continue in all areas but significant changes are IMO unlikely to be aerodynamics based, unless it's refinement of position and component interactions for individual configurations and users. (Customised aerobars, more accurate and applicable testing or monitoring of aerodynamics , and the like). Has anyone considered a tri suit that actually helps you stay in your optimum position? That could be a "game changer". Not so tweaks to frame tube or wheel rim profiles.
I don't know how revolutionary it will be, but I heard (and read somewhere on ST too from user TRIPRO) that a new bike should be announced/released in Q4. Maybe if you read this Jeroen and if timing allows for it, you could disclose a bit more?
