Adoulin missions ending points to..

[Pixela]

I personally cant see another expansion coming in the near future, as seekers of adoulin was the last game to come out for PS2 in japan before they retired it. So you gotta wonder if thats it for future big content expansions if SE are still sticking with japanese PS2 users =(

That just means no new titles have been announced, they can announce and release one if they want to.

They already stated the last ps2 title would be fifa 14 and a new title has been announced since then, PES 2014.
