It seems likely. You gotta wonder. If somebody like Mattel or Wow-Wee bought pleo, it would be all over the news. Why does no one know any detail about who bought pleo? Perhaps . . . because the company
wants to keep it hush-hush? And why would a company want to keep secret that they bought pleo? Again, any company of any size or stake in the toy or robotics industry would consider this a coup and tell the press, publicize the hell out of it. My guess is that the buyer is therefore a small company that's not ready to handle public awareness. And Vita Robotica is a robotics company that's trying to stay quiet . . .
AND . . . if what little they have leaked out includes the fact that they intend to release the PDK "in a few months" that implies they have the knowledge and skills to pick up where Ugobe left off and run with it. Who better than the people who created pleo! A big company (and I've worked in software development for some) like Wow-Wee or Mattel would take months just to get up-to-speed on the development of the PDK or the OS in order to even start looking at whether or not they even want to complete the work. And I would think a big company wouldn't be pushing to get a PDK out the door. They would be looking at cranking up production and exploiting the existing technology on their own products to recoup as much of their investment as possible. Getting a PDK out for existing owners seems much more the mindset of a small company devoted to robotics, not a big business . . .
