Prediction: Google and Sony to announce Playstation Now Support for ChromeOS at I/O
Browsing through Google's Chromium OS Reviews page and it seems a lot of effort is being put into getting the DualShock 3 to work on Chrome hardware.
Looks like it may have only started as late as April 1st (They're still working on it, so no joke), but I don't know how much prep would be required to get the service up and running. Cloud streaming service on cloud oriented devices? Makes sense to me - and it would also fall into line with Sony supporting 'Other devices' for the service.
