If you've looked at the technology in the modern Ms, you'll see a trend with technology being introduced in one & then perfected in the next:
- The E39 M5 introduced Double VANOS
- The E46 M3 had a refined VANOS & the SMG II gearbox
- The E60 M5 had SMG III & high-revving V10
- The E92 high-revving V8 & introduced M-DCT
- The F10 perfected M-DCT & introduced 1st F/I M car (I wouldn't consider the 1M the 1st F/I car b/c it used a recycled engine from a non-M 3 series)

This article begs to differ:
Same engine as 335is = N54

If you thought I meant take the exact same gearbox in the new 3 series and put it in the next gen M you're an idiot. What I'm suggesting is that its probably that we will see a completely new DCT gearbox in the next M3/M4.

^^I wouldn't go that far, especially when Ferrari, Porsche, McLaren & the GTR are all using DCTs in their cars right now. The shift times between a DCT & auto is def much smaller then it was 4 years ago.
