Well the Lancer will be in SP with Citadel, the Spitfire is based on the Heavy Weapon on Rannoch, just nerfed for multiplayer, and for all we know the Suppressor and Spitfire could also be in Citadel.

As for powers yes there are loads of nice shiny new ones, but that doesn't necessarily mean good, and we still need to use the awful pack system to unlock them. Not to mention the kits look extremely overpowered - its already bad enough when some krogan or N7 takes ALL the kills on the map.

Whereas Earth - 6 new kits, several weapons, and three new maps. and Retaliation - 14 new kits, the hazard maps, new weapons, a whole new enemy faction plus additions to others.

It seems to me that if it is the final MP pack, it should top the awesome one that came before.
