Could these be the first images of the new rumoured PS3 model? This set of images posted over at Anatel (Brazilian Agency of Communications) and snagged by Tecnoblog. The shots show a 40XX series which is said to be following the current 30XX generation of PS3 Slim models.
It appears that there is a top loading disc drive which slides rather than swallows the discs on the current PS3s. This is likely to be a cost saver, suggesting a price cut is inbound to see out the generation. There are also suggestions of two models, one 250GB and one 500GB.
