What you're looking at is quite possibly the first collaboration between BlackBerry and Android. According to @evleaks this is a render of the upcoming BlackBerry Venice, an elegantly designed Blackberry slider powered by the Android Operating System.
@evleaks goes on to say that the first carrier to offer this new phone will be AT&T.
Now as with all renders, take this with a grain of salt. Nothing official has come from wither Waterloo or Mountain View so it's all still speculation at this point. The finished product (if there really is one) could be completely different from what you see here.
However you do have to admit it looks pretty similar to the phone that BlackBerry showed off at the Mobile World Congress.
