TGS07: MGS4 with Dual Shock 3

Last week, the Dual Shock 3 was announced by Sony for the PS3. They claimed thet the Dual Shock 3 is no different than the Dual Shock 2 other than motion sensing. But Apparently, 1up seems to say otherwise.

In their preview of MGS4, 1up mentioned that "As explosions rattled around Snake, we could actually feel the direction from which they were coming based on what part of the controller virbated" confirming speculations you find all over the internet about the new PS3 controller.

So who's telling the truth here? And if what 1up claimed is true, why didn't Sony advertise that?

PS: Also, did you know that MGS4 is set in Medina, Saudi Arabia?
