They're probably taking a wait and see approach.
Great games, but Suikoden games aren't the biggest sellers so they've got to be real careful to find out which platform their base has migrated too.
A PS2/Wii port might oddly be the best option... to test how many of their fans migrated to Wii and how RPGs sell on it while still knowing that everyone who bought 3 and 4 can still get it on PS2.
An HD version would probably be too risky.
