Don’t rule out World of Goo on the DS
“XBLA and PSN will probably not happen, we just don’t think the controls would feel right. Mouse is great and so is the Wii remote. The DS would be a good platform for the game from a controls standpoint but the processor is not nearly strong enough for the physics simulation. We might be able to do a simplified version of the game, but we have no plans for that right now.” – Ron Carmel, 2D Boy
It might be interesting to see how World of Goo would work on the DS, but I personally believe it might be a better decision to move on to a brand new project. The physics part of World of Goo is one of the aspects that makes the game very entertaining.
