So we know that Bruce's most dangerous machines are not there, and also I think the fact that there are no Bat-suits shows that Blake would definitely have to do more of his own thing if he were to fully adopt the superhero thing.
But as is, he could very well just be the world's greatest Private Investigator with the help of the Bat-computer. It's pretty open to interpretation what becomes of Blake.
You could be right, but again I don't see the point of Bruce advising him throughout the movie to wear a mask. Why does Blake need a mask if Bruce is only leaving him enough equipment to monitor the city?
