That said, the M3 is on an end-of-life manufacturing process, and now that these things are getting updated every 2 years, it just makes sense to put the M3’s successor in this thing. A Pro M2 is going to stick out like a sore thumb in 2 years, and the M3s are going to start to disappear from the line up soon.
