Sony Brazil filed a registration for the new PS3 Slim on the site of Anatel (the Brazilian Agency of Telecommunications). The new model looks very cheap (and people complained about the current PS3 Slim) with rigded texture details. Also, it seems to have a toploading drive.
Just look at the pictures (got from Tecnoblog website). CECH-4011A (16GB ?!), CECH-4011B (250GB), CECH-4011C (500GB) - All with a 190W PSU. The 16GB model might be a typo.
