According to DVDPlanet.com
we have a date of 11/15/05 for the upcoming release of the complete series of Beast Machines on 3 disks. Update from Seibertron:
The set apparently will be released from Warner Brothers, who owns Rhino Video (the company which had previously released the entirety of Transformers G1 and Beast Wars). Perhaps Rhino's involvement with the Transformers isn't over just yet ...
