A New Mustang and even maybe a New Camaro?

A couple of days ago i was reading off of Moter Trend's website and I saw a story of how the mustang was going to get a makeover in 2015.  I saw some of the pictures of the Mustang and to me it looks like its just going to be a shinier and newer Evo.  But still something that I have noticed is with these pony cars is when one company changes the body style than another company changes the body style of their car.  I noticed this relevant back with cars like the Pontiac Firebird how it had a new body style in 70 from the original body style in 69.  This is also apparent with the Cheverolet Camaro how it had some change from 69 to 70.  Even Cheverolet did this with the Camaro at the time.  Oh and by the way these body styles that i am calling them re actually called generations.  But anyways, what worries me that Cheverolet may decide to go with the flow that Ford is doing and decide to begin creating a new generation for the Camaro just to give the Mustang competition for buyers like you.  I think though that now the Camaro is actually a really nice looking cars like the 12 version is really nice and in my opinion a lot nicer than the mustang.  I hope Camaro doesnt do it but i feel they will.
