Fair enough.   Every vendor has gone through their own pain with the older midplane systems in having to swap out chassis multiple times to get to higher speeds. Thankfully with the newer fabric designs we've eliminated most of that.

As mentioned you can use breakouts but to breakout 4x100G from 400G is going to require changing optics on the other side, 2x100G does not.  The 8000 series and its silicon are going to be around for a long time.

Sorry was thinking 400GE to 100GE breakout.  You can certainly do 4x10GE breakouts on the various 8000s boxes and line cards.  

Thanks,
