RIM will keep working on Flash on the BlackBerry PlayBook despite Adobe's exit from mobile Flash, the company said in a statement. It vowed to AllThingsD that, as a licensee of Adobe's source code, it would work on its own variant on Flash. Despite Adobe itself saying HTML5 was a superior choice for mobile devices, RIM was still echoing Adobe's previous attitude, saying that a complete browser needed both Flash and HTML5 to work.
