Those aren't new. They are just specific screen-caps from the TGS trailer (which has not been released in a proper HD direct-feed form yet).
Capcom, specifically said (in december) that the next time you'll see concrete new information on DMC4 is in the spring. So, the game will be in the shadows for quite some time now.
EDIT: In fact, they are actually older than TGS (well, at least the gameplay shots) Look at the HUD, for TGS and the more recent post-TGS screens, the HUD has been updated into a more mechanical look as opposed to the simpler / cleaner look you see on those screen DoomBringer posted.
Looks like sex nonetheless.
