Basically CCP couldn't be bothered to bring back the events team proper so instead masked the beta-test for upcoming Incursions as the Sansha storyline.
If any of you have played it you'll know that it was hours of sitting around waiting for intel, then dozens of jumps to the system only to find everyone ganking everything in sight with no real organization, goals or rewards in mind.
Quite possibly, but no hint at a possibility as of yet to support Sansha - as what was tried by some during the live events. Clearly we can't add to the progression of the storyline in this case.
bloke I miss you, come back to WoW!
