This is still a rumor, but gameguru claims that Valve is contemplating whether or not to develop Portal for the Wii. Portal is puzzle game, in which you shoot an entrance and exit portal to solve puzzles and get from one place to another. This was part of the Orange Box compilation and was garnered as one of the most innovating but simple games every created.

With the release of the WiiWare channel soon, I could definitely see game coming for $10-30 or maybe just at a budget price. Either way, I would love to see this turn out to be true.
