It's been available for some VAIOs in Japan, and some intrepid individuals have even gotten it working on non-VAIO computers, but it looks like VAIO users in the US can now finally get some official PS3 Remote Play support. We're still trying to track down a complete list of the computers supported, but it looks like the update at least covers the VAIO EA series, and includes all the functionality you'd expect -- streaming, Bluetooth keyboard support, etc. Be sure to let us know in comments if the update has hit your VAIO.
