“There are two videos available now for download on the PlayStation Store – 1080p and 720p – but it’s clear that the full HD video is nothing more than an upscaled version of the superb 720p trailer, and plays back with a tangible quality hit,” said the site.
“1080p has more than double the pixel count of 720p, but the filesize of the former is only about 1.5 times larger than the latter. There’s actually no point whatsoever in downloading the 1080p version as it contains more compression artifacts than the 720p version on which it is based, and takes longer to download! Indeed, it seems that the 720p trailer actually resolves more detail than the 1080p version.”
You have to get up earlier than that to catch these guys out, Sony. More detail and pics through the link.
