Another point to consider is the Hardware End of Life Announcement for
various DPCs, e.g.

PSN-2011-07-314 Hardware End of Life Announcement - DPCE-R-Q-40GE-SFP, DPCE-R-Q-4XGE-XFP,  DPCE-X-20GE-2XGE, and DPCE-R-2XGE-XFP
PSN-2011-07-315 Hardware End of Life Announcement - DPCE-X-40GE-TX

It seems rather obvious that Juniper wants to guide customers towards
MPC/MIC.
