I loved Godzillda: Destroy all Monsters Melee, and can't wait for this version for the Wii. My hopes would be that they'd balance the multiplayer a bit though, it was terrible to the game's replayabillity when someone stole your kill and scored 500 points. I'd like a percentage-of-damage based score thank you very much.
Multiplayer would also be great, they did it with the Xbox sequel to Destroy All Monsters, so there's no reason why the Wii version shouldn't be able to do the same.
