"Sly 5 Master of Thieves?"

I bring more from the Sly 5 front today with another possible leak, "Sly 5 Master of Thieves." So this image was supposedly leaked by a programmer on Tumblr. The tags placed on the image include "media," "tours," "caught," "sly 5," "iphone," "sneaky," "whoops," and "hideyourmonitors." So, lets analyze the Sly 5 logo. First thing I notice is that the "5," though its hard to tell, seems like its almost a slightly different font from the "Sly." I also notice that the "Master of Thieves" font seems far from anything on a Sly logo before. Theres also the fact that the "Sly" and the Cooper logo in the back are from another picture I've seen, and the rest was photoshoped out and the "5" is in its place. Due to these observations I find it hard to believe this is legit, but hey, ya never know!
