Default What would you do

So I currently have a note 2 and I'm debating if I should buy a note 3 of the classifieds or wait for the note 4. I'm new to the note 3 forums and not sure if the note 3 can be rooted and unlocked. The way Samsung is going, idk if the note 4 will be unlock able or even rooted. So idk what to do. My note 2 is starting to get real beat up and I don't know which route I should go. Any input would help. Thanks in advance!!!
