The reduced density is because they know most customers need tons of 10G 
and 100G, compared to tons of 400G.

So the 400G real estate is optimized for 100G (and lower) breakout in a 
small(er) form factor, rather than native 400G scale.

For that, they'll be pushing you to a chassis with a gazillion line 
cards they can sell beautiful licenses on.
