Cool, so Sony finally got around to pushing a firmware update down that allows DS4 users on the PS3 to use the following:
A) Wireless
B) Rumble
C) SIXAXIS
The DS4 is not support by Sony to work on the PS3, if it was, the things I listed above would work (and people would stop buying DS3's in droves)
Instead, the PS3 supports generic USB controllers, which is what it detects the DS4 to be and acts according. The PS3 has no idea the controller is made by Sony, all it sees is a controller.
This controller also works on the PS3, exactly the same as the DS4 does, yet it was made for PC, not a console at all
All Sony is saying by having that up is that, yes, the DS4 is functional with the PS3, however, a majority of features won't work and not all games will be supported.
