Alastair Cook. That guy's special and it's only a matter of time before he blossoms into one of the best.
Gautam Gambhir looks set to end up with a career average in high 40s if not 50.
Yuvraj Singh is typically over-rated. He is best when pitches and conditions suit him. That is okay. But he fails spectacularly when conditions are tough. He does not possess the temperament to be a good test match batsman. He will however end up with a career average in the lower 40s at best.
Ajinkya Rahane and Cheteshwar Pujara are two bright talents to look forward to.
Rohit Sharma, unless he really puts his mind into improving his temperament, will never be a good test batsman.
I watched Phil Hughes for some matches and honestly am not overtly impressed. However he's got time on his side.
Angelo Mathews is one Sri Lankan talent I am hoping to become a great.
