So it seems like those vehicle attacks are done with the same button as the dodge button, which has been movied to R1 this time around (I hope they give you the option to switch it to R2, because my muscle memory's not going to be happy

), and switching to vehicle mode is a hold rather than a double tap (as with Panther mode and its equivalents). D-pad is the on-the-fly weapon switch we all wanted in Revengeance, and apart from that it looks like business as usual for Platinum games. I don't think I saw any blocking or parrying going on, but that might just be an unlockable.
