Here's my wild conspiracy theory...the AF2 drops in Fall; October to be precise.
First mention of a development proto on the World Athletics shoe compliance list that must be the AF2 ("Dev 18240"; only approved for road races due to stack height above 25mm) is October 2021 and it lists the development period as 10/10/2021 - 10/9/2022. That shoe shows up on each compliance list since October 2021 and is listed just under the AF. If you look back at the early sightings of what looks like the final/near final AF2 proto colorway on racers' feet, it's around the same time; October 2021.
The Streakfly was also listed on the pre-March 4, 2022 compliance lists as having a development timeline of 2/14/21 - 2/13/22 and it dropped at the end of the timeline. If you look back at the early sightings of what ended up being the proto colorway of the SF, they are right in that Feb 2021 timeframe.
Cue the X-Files theme...
