I don't think that there are lots of confirmed stats yet for the Pure Aero 2026. I know someone who works for Babolat and they had the possibility to see and test the new Aero not that long ago (early April, iirc). So it is still early stages.
Fortunately for me, knowing that person, I had the pleasure of testing the frames at the beginning of May (both, 100 and 98). Of course, there was a no-pictures policy active and a "please don't talk too much about it" as well. So i will honor that. But what i can say is this: It is definitely not just a new paintjob! There are changes!
IMHO the rackets look pretty nice and they play even nicer. We had the current PA 100 and 98 with us as well, for direct comparison. For me, I like the new ones better (and i already liked the current versions). So for me, it is an upgrade. The new ones have more feel and are more maneuverable, both things that are big pluses in my book.
I am pretty sure that some people will not like it, though. If you think the current PA 98 is "almost perfect", you'll probably stick with that one.
Now if only they were out already ^^ It's such a long wait until early 2026
