Several online reports suggest that Sony will likely unveil PS3 rumble technology at the Tokyo Game Show this week.
The rumor stems from a 1UP podcast published last week in which co-host Shane Bettenhausen said DualShock 3 is "confirmed" for PS3, and that it will be officially announced at the Tokyo gaming event this week.
In early August, game developer blog InnerBits reported that rumbled-enabled Sixaxis controllers would be coming in two-to-three months. The site also said the announcement would be coming at Germany's Game Convention which wasn't the case.
Following the report, Sony responded by saying, "We have not added rumble [to PS3], and have no announcements regarding this feature."
Sony has been widely criticized for omitting rumble on the PS3, a technology which company vice president Phil Harrison recently called a "last generation feature."
