Well, as I have say im not a good Street Fighter player, but from what Ive played doing moves is a little tricky.
Yesterday I played challenge mode with Ryu and at the end I could do Hadokens, Shoryukens and Metsu Hadokens with relative ease (without using the touch scren of course). The normal combo moves they made you do (fast kicks combined ith punches, etc...) are challenging and I couldn pull them, but it was the same when I tried to do them in SFIV in PC with keyboard (lol), and seems more that you need to be good doing combos than fault of the console.
