I know that the last Bakuman chapter has been published, but listen to this:
I was talking to a friend of mine, and he found this image: http://forums.mangafox.me/attachment.php?attachmentid=213320&d=1334975569
Now, on Mashiro's left, it says the 3rd season of the anime has been confirmed. HOWEVER! On his right, it says "From April, second series is confirmed." Given that there's already an anime, it might mean that there's going to be another part to Bakuman, like how Rosario+Vamipre has Season 2. If I were to make a guess, I'd say it would be Bakuman from Azuki's POV. What do you guys think?
