Let us wish each other luck, mate! The teams in Group D are not easy opponents, especially Italy and Serbia. While I also support and cheer with crossed fingers for my very own country, I am not expecting them coming out the winner even in the first round.
They almost made it last time. They had close games with top European teams and they can do it again. I think they can win against Angola and Italy 
What about the china who is the host country for this world cup ? Although china never won the FIBA worldcup before but it would be interesting to see their performance in this WC. They are in group A with Cote d'Ivoire, Poland and Venezuela in their pool.
They may go to the second round but I don't see them going any further than that. They don't have enough athletic or deadly shooters.
