That problem IMO will only be worse with a 4x speed multiplier over 100G what premium will anyone be willing to spend to have a single 400G pipe over 4 bonded 100G pipes?
I'd say most are not willing to pay any premium at all, but are willing to adopt 4x interface speed when there is parity in cost/bit/s to bonded tech.
I opposed 40GE, but since physics is a lot of the problem here, I think 400GE is favorable over 1TE. Already now we're sitting with platforms with forwarding performance per slot that doesn't really match 100GE nicely, imagine the equivalent problem for 1TE. By the time this is ready, will platforms be at slightly over 1T per slot, perhaps it then makes more sense to have 3x400GE instead of 1x1TE per slot.
