Wow., they went out and got the original 3S voice actor for Makoto and used her for SSFIV (japanese VA.)
News is divided into three sections - the new character reveal, the iphone/ipod touch version of SFIV, and the upcoming national tournament.
The character reveal confirms Ibuki as the owner of the mysterious kunai and shows off her Hashinshou - kunai madness ultra. It also confirms Sakura as her rival.
They show Dudley and talk about his rose dubbed, "The Rose of Victory" or something like that. They say it doesn't do any damage when it hits, but it will make your opponent kind of space out for a minute (see Boxer's look of shock in the trailer) which gives you an opening for an attack. Boxer is also confirmed as his rival.
Finally, Makoto. They said that (her moves excluded) developing her was the hardest out of all of the characters and that they labored over everything from her voice recording to her outfits.
The (japanese) 3S Makoto used a special dialect of Japanese called Tosa-ben, and they wanted to make sure that they included it in SSFIV as well. This lead to a crap load of retakes but with Tsumura Makoto playing the role (the same VA they used for the 3S Makoto) they got the job done. Makoto's rival is Fei Long.
