Well, judging from the apparent lack of custom game consoles for the TS3 here on this site, I decided to go for the big kill and make one. I actually did this several months ago, although I somewhat canned it for a few months before submitting it here.

The PlayStation 3 is the third home video game console produced by Sony Computer Entertainment and the successor to the PlayStation 2 as part of the PlayStation series. Major features of the console include its own PlayStation Network service, Blu-Ray discs as its primary storage medium for games and other media, and the recently-released PlayStation Move peripheral.

I originally intended it not to be recolourable, but per MTS guidelines I had to make it as such. Only one channel, namely the console shell itself, can be recoloured, well, being that I haven't seen any striped or multicoloured PS3s yet.

Works with the latest TS3 builds; just copy the package files to your game's Mods\Packages directory. I'm yet to do the controllers, though.

UPDATE: Added patched package file for Pets and/or v1.26; anyone experiencing problems with the mod on Pets or the latest Sims 3 builds should update to the patched version.
UPDATE 2: Added Gamepad package. Note that the object is a shared asset like the cellphone, so it'll always appear regardless of what console are your Sims playing with.
