Well, PG, it's probably not as cheap as this.
Sure many coilover companies such as Bilstein already has electronically actuated shocks, but they are not necessarily compatible with the M3 EDC module. Therefore to design such a system for just one model of car may not be worth the money.
From my understanding, for a single line of products (i.e. PSS10, Moton Street Sport), most suspension companies use the same core shock design + different mounting features across many brands and models of cars. Therefore to design something specifically for the BMW M3 is quite outside their usual practice.
