:) Some translations:
1. Every boss will have minions with them.
In the picture where Ryu is holding the Dark Dragon Blade it said that you'll find it in the game.
2. The smoke bomb will have a limited number. You will have to use timing and position to use it effectively. The smoke bomb will confuse enemies. Many people will think that it is useless but it is very useful.
3. The clone battle had to be adjusted. If the clone fought like normal Ryu then it wouldn't be fair so he had to adjust it to make it fair.
There will be 50 missions. They focused on quality and not quantity. The loading times have been reduced and the game will come out before Xbox 360.
