Update: Looks like all the slots have been filled already!
Snapchat has already been massively successful on the Apple iPhone. They have a version for Android but without video sharing support.
The company seems to be close to launching a version with video support now. They invited interested users to beta test an early build on Twitter.

You can check it out right away but it would expire soon.
We imagine they would release beta builds with video support on a regular basis to get user feedback before they are set with the first stable build with video that would arrive on the Google Play Store.
