I don't think we're neccessarily going to get a Dual Shock 3.
Maybe this just opens the doors for applications like steering wheels? GT5 without FF support would be tragic.
These discussions were not related. I'm fairly certain games can get FF with a separate licence included in the game through Logitech - Logitech owns stock in Immersion and is an important partner, and Console games have become a significant revenue stream for them. Probably in these cases the licence is either paid by Logitech, or included in the price of the game. The FF driver in these cases is provided by Logitech, and not Sony (Sony is definitely a more open platform than Microsoft in this regard).
The GT:HD demo had its FF support pulled at the last minute suggests that the proper procedure would have been that per downloaded game a licence fee would have been required for FF support, which would have cost either Logitech or Sony dearly. They could have footed this bill, but with only a fraction of the downloads going to FF wheel owners, that would have cost a lot of money.
That this issue has been settled is still good news for wheel owners, mostly because it means that downloadable demos will now be more likely to support FF.
Who knows we might even get an updated GT:HD demo for download to celebrate.
Sony has proven that you can introduce a new controller later. It will be interesting to see if Microsoft takes a cue from this and the two will both release a new controller around the same time, one which brings rumble to the PS3, and the other bringing some kind of motion control to the 360.
I'm willing to bet that MGS4 will be one of the first and most certain games to support the new controller.
Personally I don't care too much about vibration (FF on a wheel is another story), but I do think vibration goes very well with motion control.
