I don't like to talk much but I would like to state the facts:
Very easy to learn yet Waaaay Very hard to master
Arcade mode is great as always, however we still miss the bonus stages
New characters are great and well developed and each has unique skills
Trials are one of the best things I liked where you have to do specific combos for each character, you can get around the easy ones, but for the hard trials you will need arcade stick and you tube 
Online matches suffer if one of the players has poor connection
Online matches available in different categories such as: Tournaments, player and ranked online
Somehow short story line for each character
Some reviews says that ryo has more advantages in the game, although I belive the game is kinda well balanced except for guile (being nerved a lot)
Overall, you will enjoy this fighting game and you will never regret playing it, if you want to master it you will sure have a lot of fun playing your favorite character and learning great combos
