Leaked information confirms that RIM PlayBook is arriving in Q1 in North America, set to cost $500

According to DigiTimes, a daily online-media from Taiwan that often provides inside information from the Asia-Pacific region, the PlayBook is set to be released in Q1 of 2011 in North America and Q2 2011 worldwide. It cites Gregory Wade, the regional Vice-President for Asia Pacific of RIM, and along with the PlayBook's release date, the article says that 4G technology will be used by the tablet, although it doesn't specify whether it's WiMAX or TD-LTE.
The BlackBerry PlayBook is advertised as the first "professional tablet" and its OS is the newly-acquired QNX. This OS is RIM's answer to its shrinking sales and it's set to be at least partly adopted by the future BlackBerry phones.
