We have seen more than few Google Babel related leaks as of late, which seems to imply that an announcement may be coming sooner rather than later. But instead of speculating as to when an announcement may arrive, lets first focus on this latest leak. This round of details appear to have been hidden in some Gmail source code.
On that note, you can take a peek at a screen capture of the code below, however the details basically include a brief description of Babel along with some features. The code mentioned how you can upgrade your chat to Babel and that there will be apps available for a variety of platforms including Android, iOS, Chrome, Google+ and Gmail. For those trying to read the code for specifics, here you go;
"Upgrade Chat to Babel! Babel is Google's new messenger with clients for Android, iOS, Chrome, Google+ and Gmail. Access the same conversation list from anywhere!"
Otherwise, the features that are listed here include Babel as being a new, conversation-based UI with advanced group conversations. There was also mention of the ability to send images and "improved notifications across devices." Basically, this just seems to sum up some of those earlier leaks.
Aside from what we have already mentioned, this Babel leak included a screenshot of the supposed interface (seen above), which appears to have a rather clean looking UI. As to where these details are coming from, the page, which can be seen in the above code has details about this being "Dogfood Confidential" and "Internal Only" at the moment. With that, we now look towards Google I/O for a possible announcement.
