As an old P1 Gen 1 user, I am surprised on the improvement of P1 Gen 7 on temperature control (SSDs keep at around 40 degree in general (full PCIe 4.0), with fast temp reduction after using ADA), on finishing (full Aluminium case), less fingerprint-prone OLED touch screen and more useful trackpad. Lenovo also add new functions into TrackPoint when you double-tap it to make the red-dot still relevant. I still miss solid buttons next to Trackpad but no chocie.
My gut feeling tell me it should be able to offer Ada 3500 with 2x SSD support.
(My Spec: i9 185, 64GB Ram, Kioxia XG8 1TB x2, Ada 3000)
