Facebook appears to have a new product up its sleeve that it will unveil next week at its headquarters in Menlo Park, California.

"A small team has been working on a big idea," said a letter sent to reporters on Friday, according to an ABC News report.

A new product will be announced at the event, slated for June 20, according to the report.

No other details were given. Facebook did not immediately respond to a request for comment on the event.

Facebook's latest product announcement came on Wednesday, when the company unveiled hashtags to let people more easily surface content around specific topics on the site.

The introduction of hashtags is just the first of a series of features the social network plans to roll out to "surface some of the interesting discussions people are having about public events, people and topics," Facebook said in that announcement.

However, whether next week's big reveal will have anything to do with surfacing content or searching across the social network in any other way is unknown.
