Well, I haven't exactly embraced waggle yet, but I think it should be optional if Microsoft actually decides to go through with this. I can see "forced" waggle being a nuisance, but if it is optional, I don't think it could really be too detrimental. The only problem is, developers would have to come up with two entire different control schemes for their games in the future. Motion controls can work and even contribute certain elements to a game, but I also think they can ruin a game obviously if they are not implemented correctly. For example, waggle could work in something like Condemned 3, but ruin Virtua Fighter 6 if they were the only control option. Personally, I think waggle and traditional gaming can coexist, but I don't think waggle should ever take the place of standard control pads since hundreds of millions of gamers(PS3. PS2, XBox, X360, Gamecube, etc.) out there are not complaining about them.
