Hot on the heels of a report suggesting the OnePlus Two will launch in the third quarter of 2015, OnePlus has decided to start teasing something for only a few days away.

On its Facebook page, OnePlus recently uploaded an image that shows an opened envelope with a piece of paper inside. On that digital piece of paper is the OnePlus logo, as well as an April 20 date with the tagline, “You’re invited!” Underneath the image, though, OnePlus also adds, “From here on out, anything could happen.”

Of course, what OnePlus could be debuting in three days is anyone’s guess at this point, especially from a company that launched a drone. But, the safe bet would be something Android related. Will OnePlus show off the OnePlus Two so far ahead of its expected launch date? It’s certainly possible.

What do you think OnePlus will announce?
