UNDATED (CNN) -- Facebook is generating a lot buzz with a mysterious press event set for Tuesday.
The social media giant has invited the news media to its headquarters to quote "come and see what we're building."
The company is apparently ripping a page out of Steve Jobs' hype machine owner's manual.
There's no shortage of theories on what Facebook will announce.
Much of the speculation is latching onto the long-rumored Facebook smartphone or tablet.
But CEO Mark Zuckerberg told a magazine in September a phone is "clearly" the wrong strategy for Facebook.
