Reply to S4 & Mic

I am waiting for my S4 in the mail and I was told they have mic inputs on them.

I will be using of course for djing and at the time with turntables as well and was wondering I might need more then 1 mic input at times. I want to use wireless was wondering what would you all recommend

Also by the way has anyone heard of a new type of S4 coming out with a booth out and other added features?
