How long until ASOP on s6?

I'm new to both t mobile and samsung phones and was wondering how long it usually takes to get stock android on the phone. I'm hoping not too long, since the phone is already rooted. i.e. how long has it usually taken in the past?

 

GAHHH, you guys scared me a lot on the boot loader being potentially unable to be unlocked. Glad to hear t mobile is the exception. I recently moved to t-mobile from verizon and I'm really loving the move so far. Getting the s6 a week early was a huge plus. I get really crappy reception in my apt, but t-mobile remedied that with a lte extender and wifi calling.

Anyways, I know everyone says touchwiz is junk, but i didn't realize how bad it actually was. Today a pop up came up while i was in the gym trying to tell me that I had my music too loud. I was furious.

Thanks for all the responses you 3.
