Samsung's trying to push their 3D ecosystem in the lead up to the World Cup. Sony - an official World Cup partner - has opted to go with their old faithful bonus offer... Buy a selected Bravia TV and get a free bonus PS3.
The offer, which began on May 1, will run until July 12, or until all 45,000 units have been claimed. There are also a few T&Cs you should pay attention to - you need to claim the PS3 within 14 days of buying your TV, for example, and there's a postage and handling fee for the PS3 delivery.
So now the question is (at least until we hear details from other manufacturers) PS3 or 3D package/home theatre system?
