Some info stemming from a recent Red Steel team interview
The team behind Red Steel have taken what was said at E3 to heart, and are trying to make Red Steel the best gameplay experience it can be. The team has stated that the controls at E3 seemed the best fit to them, but now they see that they were used to them, while newcomers found them too sesitive. The final game will also offer many control schemes and preferences so the player can be as comfortable as possible.
More swordfighting has been added to Red Steel, due to the popularity of that gameplay aspect at E3. Ubisoft claims that the final version of the game will feature controls different from those at E3, taking to heart what was heard during the demo.
Ubisoft plans to have many uses for the Wiimote speaker in Red Steel. For example, sword slashes will be heard on the Wiimote, but the team made the point to say that many more uses of the speaker will be implemented.
Thanks to Adamkula for the heads up!
