According to TheSixthAxis.com (linked above), Sony's recent PS3 Firmware 2.80 Update may have included yet another 'hidden' feature that was not uncovered in the changelog compilation... specifically, Cinematic 21:9 TV support.
To quote: "The first 21:9 TV was unveiled this year and is now available if you've got the cash to splash, and whilst the 2560 x 1080p resolution set sounds like a blessing for movie fans not happy with black bars on their 'regular' widescreen TVs, game developers surely won't pick up the better-than-HD resolution for some time.
That won't stop Sony pushing the actual XMB display out further than 1920 pixels, though - as far as we know HDMI 1.3 - the format used in the PS3 firmware at the moment - can support the resolution just fine and hopefully there's no reason why the PS3's OS can't too."
That being said, Sony has made no comment on this yet so it's essentially speculation until someone with a new ultra wide-screen 21:9 TV can confirm it.
