I still own my copy of Ogre Battle 64 and my Nintendo 64 to run it. But my TV's input jacks are completely full between my DVD player; Wii; computer; and PS2 so I have nowhere I could put my N64 even if I wanted play it. Plus, if it gets put on Wii I can play the game with a wireless controller in component video.
Hopefully, this is a sign that Square-Enix is thinking about putting more of their lesser-known stuff out there. Wasn't Tactics Ogre: Let Us Cling Together released in Japan as well? Sadly, I highly doubt we'll get that one, as S-E would have to localize it since I'm not sure if the Playstation version ever made it over here.
