Does anyone know why there haven't been Noctua X Asus RTX __90 cards?

Noctua is a premium brand, they sell premium products at a premium price. So why has the partnership with Asus only resulted in a 3070, 3080, and 4080. Surely there is a market for a Noctua RTX __90, if there's a market for a Noctua 1600W PSU.

Not really expecting anyone to have an exact answer, but perhaps someone here who understands the market better could help me get a better understanding.

EDIT: Thinking for a split second made me realise it might just be a size issue lol. Would still appreciate input though, even if it's just someone calling me dumb.
