Good question! Perhaps it has something with insane prices for the 4090? Of all 4090 laptops so far (of those I saw) none was really reasonably priced.
At that cost one can just say f it and build a more powerful desktop with better cooling solution and still have a decent amount of money left to get a solid laptop for on the go.
That's what I think at least, that OEMs see no reason to waste time and money for something that probably won't sell at all so they choose the safe route (4080).
Edit: I just went to check computeruniverse.net, big and reputable shop here in the EU, filtered out for only 40-series laptops. Numbers are:
- 4050 - 36 laptops
- 4060 - 67 laptops
- 4070 - 62 laptops
- 4080 - 32 laptops
- 4090 - 18 laptops
4090 is in barely over 8% of all 40-series in current offer.
All OEMs there with 4090 laptops:
- Razer - 5
- Schenker / XMG - 4
- Asus - 2
- Captiva GmbH - 2
- MSI - 2
- GIGABYTE - 1
- HP - 1
- Lenovo - 1
Only i9 is in offer; specifically:
- 13900HX - 8
- 13980HX - 4
- 13950HX - 4
- 13900H - 2
Cheapest two are:
- Captiva Ultimate Gaming I74-112 (1440p 240Hz, 13900HX / 64 GB / 2 TB / no OS) for 3.696,41€
- GIGABYTE AORUS 17X AZF-D5DE665SH (1440p 240Hz, 13900HX / 32 GB / 2 TB / Win 11 Home) for 3.897,06€
Most expensive is, naturally, Razer Blade 16 at over 7500€, lol.
