OEM Crank hub update thoughts

Can you be more specific? 
The design is certainly improved and looks more robust overall.
But as this came out last year or so i guess there won´t be a lot of real world data.
If your question is that you are thinking of swapping your working hub for the piece of mind, do it.
If you are thinking this vs other aftermarket solutions. This will be a bit more difficult as there most probably won´t be enough data to make a proper comparison.

I'm into a engine rebuild so swapping the hub is on the list.
Just seeking some other thoughts about the revised design of the hub with sprockets.
If the design is successful the savings on a spline lock would be quite big.

The crank hub did get changed after something like 2008 on the N54s. I looked into it. TBH the crank hub issue with regards to N54s is a bit of a strange one.
On some cars it has been an issue at stock power. On other cars running double factory HP it hasn't. It's caertainly not as big of an issue as with M3s and M4s. Is that because their timing chain drives more accessories or is it because those cars came with DCT, I don't know?
The stress\shock comes in the timing assembly needing to go from a low speed (say 2000 rpm) to a high speed (i.e. 5000 rpm) quickly. i.e. Kick down.
That shock transmits through the crank and the timing chain.
As you know ideally you should look to getting the Crank hub and timing sprocket locked so it can't spin. I don't know enough about the timing chain to know what challenges that poses. Obviously it's in 2 parts (crank hub and crank) to make removal and servicing easier.
Whole lot of speculation and very little technical analysis, despite what was said towards the end.
Will it work? Maybe, maybe not.

Only one thing is sure. A properly keyed solution will work. When that becomes necessary is still a mystery.
And that's why I decided to buy the VTT hub with crank bolt capture.
