Google is teasing Android fans again, this time with a Christmas Android video teasing unannounced docking stations for the Nexus 7 and Nexus 10 slates.

The Happy Holidays video itself is festive and heartwarming, featuring a particularly lonesome Bugdroid that gazes out of the window, while everyone is enjoying the holidays. As the holidays are full of wonders, one warm soul manages to spot the lonesome Bugdroid and surrounds it with Nexus devices showing Christmas scenes. The little Bugdroid is immediately happier and even appears to smile, and is soon joined by many other tiny Droids to celebrate the holidays among friends.

It's a nice and heartwarming story, but the video also plainly shows the Nexus 7 and 10 docks. The Nexus 10 dock is most likely a Samsung Mobile product, and is expected to offer features such as USB dock ports and 3.5mm headset jack.

Meanwhile, ASUS is apparently selling the Nexus 7 tablet dock in Japan already, but it remains uncertain at this point whether the accessory will make its way into the U.S. Google Play Store or in other markets such as the UK or Australia. The ASUS-made Nexus 7 dock offers charging, audio jack, as well as syncing with USB ports.

The Nexus 7 tablet is one of the most popular tablet PCs currently available on the U.S. market, while the Nexus 10 is Google's latest product in collaboration with South Korean electronics giant Samsung. The Nexus 7's great success is largely due to its attractive price tag, as it is the cheapest high-end tablet computer - the 16GB costs $199, while the 3G and Wi-Fi top-end version costs $299.

Google's official Android YouTube channel now teases docks for both the Nexus 7 and Nexus 10, but the accessories are not yet available. The timing of the video, however, may be an indication that the actual releases are not too far away.

Both the Nexus 7 and Nexus 10 tablets have proved to be quite popular among Android fans, and accessories are always a welcome addition for enhancing the user experience. However, Google already knows that, otherwise it wouldn't be teasing the unannounced docking ports.
