Im not aware of one. But I havent looked that hard either. I remember reading somewhere when I was in the market for a laptop that the MSI Titan has some kind of upgradeable path where the next gen they say will work in the machine. But that laptop is also gigantore and uses standard MXM 3 graphic slots.
I wouldn't mind seeing an upgrade program like EVGA graphics cards upgrade program. But you are also dealing with devices that cost thousands compared to graphics cards that cost hundreds. Im not sure it would be worth it for them to do so.
(ROG has simply become too expensive compared to the competition with same specs... 😞 )
