The Nike Zoom Vaporfly's already had set this precedent years ago: https://www.nytimes.com/interactive/2018/07/18/upshot/nike-v...
The big improvement then was a carbon plate. Adidas (and others) followed suit. The subsequent improvements since then have been marginal but the margins are thin at that level. In this case the big advancement has been the weight of the shoe.
EDIT: Also it's worth noting these shoes are $500 retail. Adidas will for sure get a boost in sales from this, but there's definitely competition in the $200~$300 marathon running shoe space that won't solely draw everyone to Adidas)
Do these new Adidas shoes have anything major over the Vaporfly shoes? Maybe they are a bit lighter?
I think the big story here may be the nutrition science to get these guys to absorb a lot of carbs during the run, more than the shoes.
