Group A Still a wide open matter. Morocco are out and only a miracle can save them, but the key matches take place in September back to back. If Cameroon pulls off 6 points with Gabon, then all damage will be undone.
Group B The draw in Tunisia was beneficial for Nigeria. It means that Nigeria have the slight advantage, but they need to improve and win at home in order to get back in control.
Group C A wide open group. Much will depend on Egypt and whether they can win away in Rwanda (which has proven time and time again a tough ordeal). Zambia is still not out of it, but they need to win in Algieria. They were the more interesting side and have more talent, but also are very inconsistent. Algieria actually really has a great squad with players like Bougherra, Yahia and Belhadj in defence, Ziani, Massouri and Bezzaz in midfield and Saifi in attack.
Group D and Group E are done, as far as I'm concerned. Ghana and Cote d'Ivoire are almost 100% guaranteed the World Cup unless they suddenly mess things up. Both team have won their key matches (Ghana away to Sudan and to Mali, while IC away to Burkina Faso). It should be easy runnings from here on in.
At this point in time: Ghana, IC, Algieria, Nigeria and Cameroon (I think they will beat Gabon back to back).
