Honestly, I'm not aware of many multiplats that are even on both Wii and PS3. The only notable one I can think of is Winning Eleven, which Konami's done literally everything in their power to shift audiences towards PS3/360, while rebranding the Wii title and generally releasing it months later. The damage there is pretty much done at this point. There's also Sonic Unleashed, but those releases are somewhat different between SD and HD content wise, plus the Wii version (barely) sold best there anyway.
I do think Basara 3 will do better on PS3, but that's largely because Koei's already consolidated the Musou fanbase there (which Basara takes after).
