"Multiple hit-absorption focus attack becomes possible!
A "Red Focus Attack" which allows you to absorb multiple hits has been added! It costs super gauge to use, but the damage and ultra gauge gain become higher than from a normal focus attack! Of course, you can dash cancel it as well."
ComboFiend over at Capcom Unity also posted a video in which he explains the Ultra Combo Double and Red Focus systems. He also states that the Capcom team has successfully removed unblockables from the game, and that we will indeed see location tests for USF4.
