Wink [Q] warranty safe root (KNOX safe) -- will there be such one for S5/4.4.2 ?

I am just thinking if to root or not right now. You know that would be pity to know that they found a warranty safe method of obtaining root right the day after you got it with KNOX burnt to 0x1. So if developers are about finding some exploit or something like signature (hehe, that was the case with sony psp), i'd wait for some time =)
