Some info from the person who played it already:
During the missions you can collect medals. The better you play the missions, the more medals you can collect (going from bronze to silver to gold). You can collect up to 3 medals per mode.
Medals count in the ball bonus count, but also at the start of Kobayashi Maru. For example: all bronze medals collected gives you a 15M bonus at KM start.
Vengeance is deeper. Vengeance 3 is no longer a hurry up but a mode where you can earn 10% of your score when playing it right. With some tactics (i believe combo/double playfield) you can even boost it up to 40%.
Lighshows are nicer and more polished.
Asteroid flashers are now fully implemented during gameplay.
Carl speech seems less loud now but this can be an impression.
