Manda can not play chess, he has no arms
The storyline seems so obvious, how can people make so wicked predictions. ._.
Tobi - who's the man in the shade who was talking with Pein - has already got a sharingan he somehow stole from Uchiha Madara a long time ago, and is going to take the last three sharingans in the world - kakashi's and the two last uchihas. It will make him the most powerful fighter ever (1. 4 sharingans = imba 2. he will be the only person able to use sharingan, knowing sharingan's only weakness is another sharingan). Everything was planned long ago; since Akatsuki has good info they knew already about the nature of the bonds that tie Sasuke to his brother. Sasuke isn't chasing Itachi, but actually Akatsuki's leaders are dragging Sasuke to them using the hatred he holds towards Itachi. Remember that Akatsuki is 9 years old
