I'm really liking this combo series and think they'll be really good for newer players.
But there are some combos that I would have liked to see included. For Kyo, his corner air Orochinagi -> fireball -> running grab combo gets used in matches a lot. For Goro, his EX throw into corner, followed by three multiple df+Cs is one of his better combos. And for Benimaru, the above-mentioned air Raijinken HD combos.
These are just nitpicks, of course.
