You are getting a newly designed playstation controller. Its called the 'Arc', lol.
All kidding aside, they were already making one for the PS3, but it got such negative fan reception they just backpedaled and kept the old design. Frankly, looking at Sony's track record, they don't seem to be able to come up with much original ideas. They'll probably have to wait until someone else comes up with a 'new' controller and just slightly tweak that. I mean, every one of the previous Sony offerings in the past has been a previous Nintendo idea altered to work for their machines.
