Konami recently reupdated his Suikoden Portal Website .
The display of the site also changed a bit from the previous update.
Before the update, the last time an update was posted on the website was on June 18, 2014, when the “Best Collection” version of Suikoden I & II for PSP was made available as a free trial for PlayStation Plus subscribers in Japan. Before that, the last update was on November 21, 2012, when the “PSP the Best” version of Genso Suikoden: Tsumugareshi Hyakunen no Toki was dated in Japan.

Not sure what this sudden re-interest for the site means, but let's hope for the best.
