We saw him last year at Toy Fair 2016 and this year the show, Spinmaster brought with it an Astro-mech droid. Yes, their BB-8 Unit was back and will be released later this year.
It is powered by an AC adapter, one for the head and one for the core body. BB-8 stands tall, but not as tall as the actual droid. It has a speaker inside and a microphone, allowing it to respond to voice commands.
If you mention Kylo Ren or a Stormtrooper, the droid will back away, plus it even has a follow me mode with obstacle avoidance built-in.
Spinmaster’s BB-8 will cost $229 when it ships later this year.
