They don't look seven days long by comparison, Nikita :P
Yes, CCP has gotten ham-fisted with the presentation of their ingame content. This is largely in response to its market; the stories are all written for the existing market and not what we seek to turn it into.
And yes, it does mean that there's more visibility for the Nation, but frankly, they need it. The other factions save the Angels are historically played up just fine with the history of events and AURORA storylines; the EoM and their counterparts (whom you may not even be able to name because you only know about the EoM by virtue of the freakish love the Amarr bloc kids lavished on their corner of the PF - I only dimly remember the Caldari and Matari ones myself) don't get touched because they're mission-writer content and not really pirate factions, and historically there's been some talk of the Devs having a shortlist of factions - the Ammatar included, for example - that are curiously largely untouched except in world-level events, which is suggestive of long-term planning on their part.
Wasn't there quite a bit of mention elsewhere of other factions getting in on the incursion action eventually?
