Grant:

Hopefully they will start to make M4 CSL and M2 CSL in the next generations of each (rumored to be case that they make 4 versions of each, M2, M2 Comp, M2 CS, M2CSL, and same for M4)...

Hopefully, they will make the price jumps more modest next time or the M2CSL will cost more than double M2...

 

That sounds nuts.I already have difficulties to understand the differences between these variants, apart from the engine type and output. Looks to me as if they did not want to make the price difference  between M2 and M4 too obvious, as the CS already has the same performance numbers.
