Portuguese-language website Dudu Rocha Tec based in Brazil is running Google's software on BlackBerry's hardware on YouTube and shows off the fluid experience along with some BlackBerry add-on apps, which you'd expect to see.
It looks like BlackBerry is taking a sensible approach by not "skinning" the base Android interface.
Instead, the company is keeping things simple and consistent which can also help with performance: The more software add-ons integrated into Android, the more risk a hardware maker faces by slowing the phone down.
Google apps are present in the video, indicating that BlackBerry has licensed them like any other Android partner.
Of course, this isn't -- and shouldn't be -- a pure stock Android experience.
You can see various BlackBerry apps in the video and I'd expect the company to use its BlackBerry Hub as a default application, providing quick access to consolidated communications. This feature is one of the best parts of the BlackBerry 10.
