Default S4 Root Status

Well I broke the screen on my fully rooted and unlocked boot loader Galaxy s3.
My question is at the price to fix my s3 or get a s4 is going to be cheaper to just get a s4
but where are they at on rooting this device from what I see the software is up to MJ7 but the boot loader is still locked unless you have older software like MDK is this correct.
