i like its design it looks more like a traditional console instead a pc. The only problem is the piano finish and the countless close groves around the console which are exposed to dust.

they definitely could make a new model which could end up being quite a success. They Should make the console smaller just like the Wii U is, which has the same CPU architecture. They just have to remove the powersupply and make it external.
They also should change the controller, make it a PS3 controller but in a PS4 Design using the same Plastic shell etc.

PS2 Slim kind of resembles the PS4 a little. PS3 super slim is pretty slim for what the console does. Don't think it needs to get any slimmer.

If Sony were to come out with a slick, good looking new PS3 model for around $100, with a decent amount of internal storage, I wouldn't be able to object. Not a single bit. Day one buy.

PS3 Slim is my favorite it would be cool if they made another one.
