Sony are planning to update their PlayStation 3 to allow it to have support for 4096x2160 (4K) content. It will only be still content, but showing off some super high resolution photos on a 4K-capable screen or projector will look insanely awesome. The firmware update is planned for early 2012 and will let the PS3 support native output of 4K stills. The PlayStation store in Japan already has a PlayView "visual magazine" which supports both 4K and 3D.
This new update will allow any high resolution image to blow up to 4K resolution. Obviously you need a 4K-capable display or projector, but at least if you have the cash to spend on a 4K screen you now have something to use your PS3 for other than gaming and Blu-ray movies.
