We learned earlier today that Google is launching a social status update feature in Gmail. While details are sparse, The Wall Street Journal reports that it is a new Gmail module that could integrate status updates as well as content from YouTube, Picasa and potentially other social sources. WSJ is unclear as to when it will launch, though.
We think that Google's new social status feature will be announced tomorrow. We have just received an invite to attend an event at Google's headquarters where it will be "unveiling some product innovations in two of [its] most popular products."
The description fits very well with the WSJ report. Gmail is one of Google's most popular products, and this new social status update feature would be a "product innovation" within Gmail.
As for what the other product getting new features may be, we can't say for certain. Picasa, YouTube, Google Friend Connect and Google Accounts all seem like potential candidates.
