It's no surprise to hear that Sony's already working on the next gen PS3, but rumor has it that the new PS3 will have a dramatically different design from its current incarnation, shedding loads of that initial baby fat for a nice svelte profile. Sony Japan says that they're expected to transition to 45-nm chips by 2008. These new chips would halve the size of the PS3's current 90-nm chips, allowing for that thinner, curvier PS3. Considering how fat the current model is, the idea of a slimmer console is a welcome idea indeed.
