It isn't though.

In the prototype, there's a model label saying "N9":


Also the E7 looks much more finished, complete. And more droid-like in shape. Well, to me, anyway.




I believe prototypes generally are equiped with 0s instead of future model numbers at Nokia? Like the N00, etc.

To me, the "N9" photos seems like a build prototype bragging to be more than it is. Not quite an N8, not quite an E7, and probably not quite the N9 either.
