Why are you so focused on the rooting? Seriously? This was a contingency that would need to be addressed IF and ONLY IF the marketing showed that there would be bloatware installed i.e. proprietary software that blah blah blah is required blah. Then, when they release a technical sheet I would want to know if it has an unlocked bootloader. This is easily done, the same way every other manufacturer does it, by ending it to forums to test i.e. AndroidForums.
However, as I stated, the s-lock is MY REQUIREMENT to be met IF they load the phones with shitty software.
