While we're limited to merely 3DTV depictions of the 2010 World Cup , Japan is letting its freak flag fly in a proposal to host the 2022 matches with a concept envisioning matches captured by 200 HD cameras, then projected as fully 3D images onto real fields in other countries. Just in case technology hasn't advanced that far in the next decade plus, there's also the possibility of positioning mics underneath the playing surface to catch every sound, with all of this powered by solar panels plus the kinetic energy created by a stadium full of fans. Even committee director of technology Jun Murai admits the proposal "smacks of science fiction" but seriously, this is Japan we're talking about -- if the beautiful game is still being played by non-augmented human beings and not a squad of robots we'll be surprised. Either way, someone should put Wolf Blitzer and Will.I.Am on standby just in case.
