My first Alieware was a 4th gen i7 with 780M 17 inch machine and currently I'm using the 7th gen i7 with 1070 model, both are top class machines, there's no real competitor at the still reasonable price.
I was seriously considering the M18 last year until I got a chance to see the unit in a retail store, the M18 model with RTX4080 overheated in less than 3 mins of gaming, under 25C room tempreture, the CPU went straight to 100C. The M18 design simply could not handle the 13th gen i9.
Now, on this M16 R2, the cooling and preformance with drop further, what's the point?
The point is reduced manufacturing cost, amongst super heated gaming laptop competition, if you look at the Alienware prices in China, the M18 and M16 R1 is priced above $3,000 USD, top unit is priced above $5,000 USD, the price almost doubled to previous generations.
Now, interestingly, the M16 R2 is priced at $2,000 USD(R1 is $3,000 at same spec), why? Because competitors are no longer falling behind, the ROG performed super good with their G14 and G16 recently, and with only half of the price compare to same spec-ed Alienware models, the Alienware simply could not sell! That's why DELL eagerly to roll out a new model, and that is M16 R2.
