The main feature that Incursion is supposed to deliver is the multiplayer Sansha incursions for which the rewards are LP from Concord. These LP can be spent on blueprints for shiny new named capital modules, meta level 2 items that will give dedicated cap.
Now, we're all very familiar with the named items dropped by rats all over new Eden, many simply end up recycled because they're so darn common, while a rare few ( Mining Upgrades, Shield Boost Amplifiers etc) are worth silly amounts of money. Some very common modules don't have named versions - Remote Hull Repair systems are the most prominent example, you can't even invent a T2 version of those (fix this!).
Until the announcement of the new capital modules I thought CCP had forgotten about the named items. With the magic of the item database I can go and look into the history of Eve to reveal that the most recently added named item were Heavy Assault Launchers and Signal Distortion Amplifiers. These were added to the database about the same time as Salvaging, so that dates it to the Revelations expansion back in November 2006.
