There aren't any launch details at this point, but Nikkei says that Sony will open up the dog's software to let third parties add features much like they can add "skills" to Amazon's Alexa.

Reportedly, this home robot wasn't guaranteed. Sony was thinking of making industrial robots, but decided that the market was too well-established to let in a newcomer. In-home robots are still relatively fresh, offering Sony a better chance at success. If this Aibo pseudo-sequel does take off, it'll join a personal robot renaissance in Japan. The country developed a strong early reputation for robotics through machines like Aibo and Honda's ASIMO, but that tapered off as AI from the era hit a wall and companies like Sony ran into financial trouble. As you may have noticed, though, AI is enjoying a resurgence thanks to progress in machine learning and products like smart speakers -- Sony and others are coming back knowing that the technology is much more practical for everyday use.
