Topic is situation of current youngsters, their rankings - how do they climb it, their chances in 2013 and many things connected with it.
Goffin, Klizan, Raonic and Nishikori will continue to climb the rankings slowly and maybe Raonic or Nishikori will finaly get into that top 10 ranking next year. Klizan and Goffin probably inside the top 25.
I doubt there will be a major breakthrough for anyone, no slam SF for anyone younger than Delpo next year.
Dimitrov has shown signs of small steps forward, he can climb into the top 40 I think and maybe finaly win some small tournament, but probably not. Harrison will stay where he is, Tomic will fall to a deep hole next year.
Janowics and Kuznetsov moving really slow not to make any sounds this year will climb to top 50 by end of next year and maybe we get to see them play in some R16 in a slam or SF of small tournament.
