For a while now, we've been hearing about the BlackBerry Desktop Manager replacement that will be coming with BlackBerry 10 called BlackBerry Link. We've seen some shots of it here and there but now, the latest Dev Alpha update pushed out is showing signs of it as well. As you can see in the images, BlackBerry Link even tries to install when the Dev Alpha is connected to the computer. There is bits and pieces of info throughout the files such as:
BlackBerry Link 1.0 supports new mobile-enabled BlackBerry PlayBook tablet. With the BlackBerry Link 1.0, you can create a backup file that was created while using the BlackBerry Desktop Software for Windows, restore your BlackBerry smartphone or tablet. When syncing contacts the BlackBerry Desktop Software also maps groups from your Apple Address Book to a category with the same name in the Contacts application on your smartphone. For more information, see http://www.blackberry.com/desktop/docs/.
[This particular file isn't in English so I used Google Translate to see what it says]
It will go so far as to offer to install updated drivers and quit there. If you poke around a bit though, you can find the set up file needed and run it. However, BlackBerry Link won't fully download and install because the webpage for it isn't quite live yet or it's based off an internal RIM server. Either way, it adds just a little bit more confirmation to its eventual arrival.
