It's certainly not a confirmation by any means, but a recent job posting from Netflix seeks an experienced engineer for "developing and testing media rich applications on current generation gaming consoles."
If you read the entire job posting, it is pretty clear that Netflix is talking about consoles in the plural sense. If the plural is in fact, not a general term for game consoles and they're not juts updating the 360 version, it most likely means the PS3 and the Wii. Whether this will become a reality anytime soon is not clear—but we know that they have an interest in branching out beyond the Xbox 360. [Netflix via Crunchgear]
