Will i get abs in 2 months. Please answer?

Im 15 125lb 5'10. If i do the p90x ab ripper x then my own ab workout which has 690 crucnhes in all. They work all abs. Im thinking of swithching because i hearrd that your abs get used the same exercies if you keep doing them. If i do ab ripper x one day and my own the next will i get abs. I do my cardio in track. Please Answer i have 2 months
