Viegas, the president of Immersion, the ones who sued Sony for illegal use of their force feedback engine, criticized the PS3 controller for not having the rumble feature.

“We had a lot of employees on the floor at E3, and many of them got to get their hands on the [Playstation 3] controller,� Viegas said. “They say it felt light, that it felt cheap and flimsy, and that it lacked weight or substance. Overall, they were disappointed.�

He also spoke with some of the developers’ thoughts on the Dualshock 3:

“I’ve spoken with a lot of developers, and apparently out of the early kits they were given to work with, at least a few of them contained vibration technology,� Viegas said. “When the announcement was made that the final product wouldn’t contain that technology, they were as shocked as everyone else.�

So, what about the Wii?

“We have officially stated we have not performed full analysis on Nintendo’s product so are not in a position to comment on the technology they are using,� Viegas said, adding “we’ll take a look at those.�
