it' not like this is new info, but the problem is the condition Kakashi is in. Also he seems to be affected a lot emotionally, which will become a problem for him, when he must fight a cold harded obito, who wont hesitate in ripping him into pieces. however, it is kakashi we are talking about, so he still got a few moves left... you never know what kishi might pull out. I, however, could see the kages possibly more allied forces joining up. Kakashi wont last another 5 minutes of battle.
People think this battle will be one on one battles.. How long did it take Madara to get from battle with kages to there? Not long.. How long have the allied forces been on the move towards their battle field? They were on the move even before Sasuke met Itachi.... Stop saying bs.. Unless someone stops them, they will arrive within next few chapters, and it will be before sasuke U_U
