Call it educated speculation based on years of experience with similar decisions.
How big is the team? How many years of maintenance have you had on those projects? I remember C++ looked pretty awesome for a while. It was certainly great for one-man projects or small team. Then the problems started piling up. Thing is, C++ didn't have any good alternatives (maybe now we'll have Rust); Scala does.
