There's not much you can do right now with an unlocked bootloader as far as i know so you might as well wait it out. At least until we have TWRP ported and you can actually root. Maybe by then Moto will pass along a definite answer.
I'll probably wait it out too. I was disappointed that my phone won't be delivered till Monday, but, as of now, there is no official root or custom recovery.
I don't even know if the stock firmware images have been posted. As much as I want to start playing with the phone, it doesn't make sense to retire my Nexus 6 just yet.
