Africa image from WikimediaFollowing up on a story we reported last week about preparing Africa for the World Cup in HDTV, Sony released some news about the 4k (or 4,000-plus-pixel capable) projectors they demoed at this year's World Cup broadcasts in South Africa. Using a projector that is capable of 4k resolution (four times the normal 1080 lines of high-definition resolution), Sony claims their Silicon X-tal Reflective Display (SXRD) projector helped with the first live HD transmission on the continent.

The projector can drive either four different 1920x1080-pixel screens, or be combined into one 4096x2160-pixel monster display. At up to 18,000 lumens, it's also obviously designed for outdoor venues and movie theaters, but it's great to see yet another area getting exposure to the superb detail and color of high definition. We thought HD was all over the place for the 2006 games, but it's clear we can expect even greater display and broadcast technologies when the 2010 games roll around.

Do you think we'lll have to wait for the World Cup games in 2010 to get the ultimate in HD display and transmission technologies like these, or will all this be old news by then?
